Bringing History Back to Life

This section of the website is dedicated to journalling the computers I bring back to life (or my failures in doing so, where appropriate!) I got into this in early 2019 when I determined it was time to revive my original Mac Plus that has traveled the continent with me for two decades, slowly losing its will to live. I learned a lot doing that — and managed to avoid electrocuting myself — then decided it might make a fun and profitable hobby for my son and I.

As you’ll see from the entries, the profit part is usually missing, but restoring these little bundles of computer history has other rewards. Plus, having a hobby keeps me (and Nicole!) sane.

You can scroll through the post history in the section, and see them all, or use this index to jump to your favorite machine…

NeXTstation

Steve Jobs followed up the Macintosh by getting forced out of his own company. In response, he started NeXT — and took some top talent from Apple with him. The new company created a 1 foot, solid black cube, then loaded it with a Unix-derived Mach microkernel, aiming the whole thing at the “Workstation” market. Exactly what that market was became an issue for the company, but they did have some important customers: John Carmack created Doom on a NeXT computer, and Sir Tim Berners-Lee created the World Wide Web on his Cube.

Despite its unwieldy size and disappointing performance, NeXT cubes remain a sought-after collectors item — one recently sold on eBay for over $3000. I was lucky enough to get my hands on the follow-up machine, called the NeXTstation (or pizza box) for a fraction of that price. Of course, it didn’t work, but that’s never deterred me before. While it started its life at the University of Pittsburgh, it had spent its retirement years in storage. I met the seller halfway to Pittsburgh for the hand-off, brought it home, and fired it up to a diagonal line pattern, reminiscent of the “checkerboard” display on a dead classic Macintosh.

After all the normal maintenance tasks, like cleaning the logic board, and re-seating the RAM and anything else removable, the first order of business was to isolate the problem — was it the monitor or the computer generating the image? Unfortunately, without parts to swap, this was hard to do. The NeXT is a complete system: the monitor gets its power from the computer, the keyboard connects to the monitor, and a key on the keyboard tells the whole thing to turn on; there’s no power switch, and no easy way to fire up the system without the monitor. I ended up looking-up the pin out for a VGA cable, then splitting out the specific pins for the video signal (the NeXTstation is monochrome, but all my VGA monitors are color, so I ran the video signal to green) to another display, routing the rest back to the original monitor for power and keyboard. This hack allowed me to get an image on a known-good monitor, verifying the issue was with the computer, not the display.

Impressively, but unfortunately, the design of the pizza box is quite sophisticated: there are very few independent parts, and short of re-capping and re-chipping the whole logic board (the latter probably near impossible) there was really no repair that could be done. Fortunately, Black Hole, Inc had new-old-stock logic boards available, and sold me one for a reasonable price. Once installed, the NeXT sprang back to life — and demanded a password I didn’t have. The owner at Black Hole has all the old documentation online, so I was able to hack my way in, reset the password, and configure basic networking. I was amazed that the Quantum Fireball hard drive was still spinning — but didn’t realistically expect it to last long, plus it had no space for an OS upgrade. The machine came with NextStep 2.2, but I wanted to get to at least 3.3. A SCSI2SD was in order… getting it working was another ordeal.

Instructions in the forums provided the necessary information for configuring the SCSI2SD, and after some fidgeting, it was recognized by the machine. Black Hole sold me a SCSI DVD-ROM, and I burned an ISO of NextStep 3.3 using a more modern computer. To connect it to the system, I used an old hard drive enclosure for a Mac, and a SCSI 2 to Centronics cable. I also had to raw-write a boot floppy image. The floppy booted, handed off to CD, which formatted the SCSI2SD without complaint, then wrote the NS3.3 bits to the SD Card. Everything looked good until I tried to boot from SCSI2SD — the system would just hang. After repeating these steps, with minor variations, and messing with SCSI termination, I finally just pulled the SD card out, plugged it into a modern Mac, and with some help from this blog post, used DD to write a pre-made NS3.3 image to the card. Once re-installed in the NeXTstation, everything worked perfectly. I needed a mounting bracket to make the SCSI2SD sit securely in the case — but fortunately another hobbyist had published one that was a fairly quick 3D print away.

The final step was to pull anything valuable off the old hard drive. For that, I rigged up a FTP server on my G4 Cube, and command line “put” things from the old, then “get” over to the new. The machine came with Mathematica 2.2, which I badly wanted to play with, but the license was invalid, and Wolfram was unable to help with a replacement key. I worked around by extracting a copy of Mathematica 1 from a NextStep 1.0 disk image I found online.

Copying stuff back and forth via FTP got to be a pain, so I setup a NFS share on my Raspberry Pi, and got the NeXTstation on the network properly. I even managed to connect to a network printer. I also rigged up a companion Virtual Machine, running OpenStep 4.2 on a modern computer that functions as sort of a bridge and place to experiment with new ideas. I really, really like this operating system, and the portability between hardware platforms that became so useful for its future.

Although NeXT failed as a company, they were acquired by Apple in the late 90s — providing an infusion of needed tech, and a way to get Steve Jobs back in the captain’s chair. After a few false starts, NeXTStep (aka OpenStep) became the core of Apple’s OS X, and in turn, the core of iOS, iPadOS, and tvOS. All of Apple’s successful products for the past 20 years trace their lineage to this black slab, and its quirky but powerful operating system. For these, and other reasons, the NeXTstation likely has a permanent home in my collection.

Software and bits I collected during the restoration can be found in our Public OneDrive share.

Atari 1040 ST

This is likely to be my last post about 16-bit Atari — I did not enjoy my time with these computers (despite lusting after them for so many years.) I bought this to troubleshoot issues with my Mega ST 2, and did the requisite service, but this was not a machine I fell in love with.

The machine came with 1.0 TOS ROM chips, and evidence of some historical power supply blow-out. I upgraded the operating system — by yanking out the aforementioned chips and installing new ones, re-capped the power supply, and scrubbed as much carbon scoring from the case as I could, before a gentle retro bright bathe.

The matching monitor I acquired through the Mega ST deal, but it was too difficult to disassemble, so I tried a new retro-bright technique. This one is mostly about a pure soak in the sun, but augmented with an occasional application of 40v diluted with water (about a 80/20 mix) applied liberally with a paint brush. The theory here is that its actually the heat that is the catalyst for color change, and I’ll be honest, it worked quite well. A liquid bath is still preferable, but I’ll adopt this technique going forward for devices with challenging disassembly and low value.

Everything cleaned up nicely, but multiple attempts to acquire a matching mouse failed. I settled for a PS/2 adapter, and a white PS/2 mouse. I also purchased an unfortunately named device called a “SatanDisk” (not to be confused with the superior “UltraSatan“) so I could load up my curated hard drive image onto a SD card adapted to the Atari’s hard drive connector.

Because this model did not include an RF Modulator (that wouldn’t be available until the 1040 STF) getting color out of it with a modern display is challenging. I purchased a cable from England that worked with one of my VGA monitors (although the monitor permanently displayed a warning that it did not prefer the Atari’s 15 khz refresh rate) and tested color. I also cleaned the heads on the floppy drive, and tested it.

Ultimately, I didn’t keep this one long — it was less capable than the Mega, and frankly underwhelming compared to Apple machines of the era. The bundle sold for about what it cost to put together, although I lost a little on eBay fees and shipping. I’m glad I got to play with one, so I’ll know better than to buy these in the future…

Apple IIC Plus

The Apple IIc+ occupies an odd spot in history. It represents the final iteration of the Apple II, and a slightly modernized twist on the portable Apple IIc (while shedding some of the portability that came with having an external power supply that could be replaced with a battery pack), increasing the clock speed and swapping out the 5.25″ floppy for a 3.5″. I’m not sure who the market was for this machine, since the Mac was well entrenched by this point (it even shares a naming convention with the Mac Plus, released the previous year). I guess it was kind of a swan song to the fans.

Cosmetically, I think its the most beautiful of the Apple IIs — already in a sleek design, the matching keyboard made the whole thing look more cohesive. Having a more accessible floppy disk format (and the fact that it could boot from either the internal drive or an external one) is nice when doing a restoration, but was probably frustrating for users at the time since most Apple II software came in the older format. The clock speed is a similar trade-off: yes its faster, but so much faster that lots of games don’t work properly.

I bought this unit from a Goodwill auction, missing the “2” key and the Apple logo. Apple Rescue of Denver had a 2 key from a standard Apple IIc that was a little off-color, but physically fit; they did not have the Apple logo. Everything worked when it arrived, and it was in excellent physical condition. It needed only a short, heavily diluted retro-bright bath, and some cleaning between the keys.

I re-capped the internal power supply, and cleaned the floppy drive. I got to play with MouseDesk on this unit, using a Floppy Emu and a mouse from my Mac Plus, but otherwise, could find no long term use case. The sale price will put me ahead, after parts, fees and shipping — but only on this one project. The surplus will immediately be applied to my NextStation restoration effort… those parts are expensive!

Atari Mega ST 2

When I was young, my parents wanted to encourage my interest in computers, but couldn’t afford a new machine, so they bought a used Atari 800XL from a friend, and mostly let me have my way with it. My dad writes about being shocked when I took it apart. Of the many things I learned how to do with that Atari, war-dialing BBSes was one of my favorites. It was through these proto-online experiences that I learned about the Atari ST computers. I remember being shocked that the “1040” was a computer more powerful than mine — because my floppy drive had the moniker “1050.” That year, I asked a mall Santa for an Atari Falcon.

For more than two decades, I’d lusted after these fabled 16-bit Atari machines, but their relative rarity in North America meant they were too expensive to justify. I finally found a fellow nerd who traded my restored Apple IIGS for his Atari Mega ST 2. My excitement faded fast as I figured out why Atari didn’t survive as a purveyor of home computers…

My Mega ST set-up came in stackable parts: the main computer, an external Megafile hard drive, and a high resolution gray-scale monitor. 2 of 3 parts were very yellowed, but in otherwise great cosmetic condition. The monitor sprang to life clear and sharp, the hard drive spun true, and the Atari itself booted quickly — but screamed the whole time. I figured this would be an easy repair, if that was the only issue.

Dissembling the monitor proved too difficult to be worth it, so I tried a new retro-brighting technique: mostly a pure sun bath, combined with periodic painting on of some lightly diluted 40v liquid. The color was mostly restored, and there was no bleaching or staining. The Mega was easier to take apart — save for the ridiculous amount of metal shielding. The keyboard was similar, although I was horrified to find that each individual key-cap had its own separate rubber plunger, most of which rolled away and had to be chased across the rec room. My standard gentle retro-bright bathe cleaned these parts up nicely, and the color match with the monitor was spot on. While they were apart, I re-capped the logic board and power supply, and check continuity on the keyboard solder points and cable — since the screaming sound appeared to be a “stuck key” indication.

Next came the hard drive. Amazingly, the case color was still quite close to original, and even more incredible, the factory warranty stickers were unbroken. I decided it was best not to mess with it, and settled only for a warm cloth wipe down, and a gentle baking soda rub on a few stubborn spots.

Once everything was dry, I re-assembled it all and powered it back up. Same quick response, same screaming sound. I purchased a new keyboard cable from someone online, and waited to try again. Weeks later, same result. After repeated attempts, I found that 2-3 times in 10 boots, there’d be no scream, but any text entry field would immediately fill up with garbage character input from the keyboard. And 1 in 10 boots everything would work fine. Occasionally disconnecting and re-connecting the keyboard after booting would solve the problem.

A YouTube video indicated a possible short or unintended ground on the logic board might be the culprit, but running the Mega bare on a static mat had no impact, and a close inspection with a loupe could find no bad traces. A fellow nerd suggested maybe a bad oscillator crystal on the keyboard, but swapping that fixed nothing. A replacement keyboard could only be sourced from Europe, at great cost, and with significant delay due to the pandemic’s impact on shipping. Finally a member of a Facebook group who’d purchased a previous restoration from me volunteered to send me a cap-less junk keyboard that I could use to narrow down the problem. Sure enough, the Mega was happy with that keyboard… unfortunately, the caps from my bad keyboard were not a fit, so I couldn’t combine them. Instead I swapped every significant electrical component from the working-junk keyboard with the bad-but-beautiful original. No change.

Determined that this project wouldn’t be a complete loss, I purchased a hard drive emulator (unfortunately dubbed the “UltraSATAN”) so I could load up some games… only to find that the disk would get corrupted within minutes of use. Discouraged, I found and purchased an Atari 1040ST to try to compare and isolate this problem. Eventually, I learned through forums that reliable hard disk access would require an OS upgrade. Incredibly, Atari’s approach to software updates was to replace ROM chips inside the computer — I ordered some from eBay, and after two tries, got a set that worked. I found a decent list of games that claimed to work in high-resolution mode, and curated a hard disk image using the Hatari emulator. About half the games were playable, but even less were fun. Oh well, maybe I need a color monitor for the fun ones…

This, it turns out, required an expensive custom cable, so it was back to eBay for an Atari video to SCART cable. Fortunately, I had an SCART to HDMI adapter that had served me well in the past. Unfortunately, the hand-made cable arrived with a short in it, and within minutes of plugging it in, smoke was pouring out of my HDMI adapter. The seller replaced the cable, and I bought a cheaper adapter on Amazon… which only showed one color. I returned it, and bought the more expensive adapter again. Finally, Atari in color on a modern monitor… at this point, I was so far in the hole on this project, that it was impossible to justify it to my wife/accountant.

My original goal had been to play with some MIDI software. I used to play piano quite well, and remember when I first learned about MIDI keyboards and got excited about this union of two of my interests. While our current Clavinova does MIDI, its of the USB variety, and adapters from USB to classic MIDI are unreasonably expensive. The only use case left was to try out some more games… unfortunately, the Atari joystick that had been in storage since my youth only had one working axis. Off to Amazon to order a replacement.

We did finally manage to try out a few games and have a little fun with the beast, but most of the joy, and all of the excitement was gone. Off all my restorations, this one is most clearly a failure. The Mega ST 2 looked and ran nice, and I found a buyer for it who already had a working keyboard, so I’m sure he was happy. The Megafile hard drive worked great, and another buyer got a decent deal to add to his collection. After selling, I got close enough to the break-even point that the boss allowed me to continue with other projects. And I still have the monitor and the 1040ST to play with… but those are another blog post.

Macintosh Color Classic

The Color Classic was the compact Mac that the fans wanted… almost. It unfortunately ended up with a slightly crippled system architecture — something only addressed in the Color Classic 2 (which was unfortunately never sold in the US.) Still the Color Classic (CC) was a cute and modernized take on the design that made the Mac famous.

Running the penultimate non-PPC Motorola CPU, the 68030, but limited to a 16-bit data path, the CC is poky on later versions of System 7, but runs well on 7.1. Its display does 256 colors, but at a non-standard resolution that prevented it from playing a significant subset of color Mac games (although its possible to work around with a pretty heavy-duty hardware mod that ups the display to 640×480). The CC shares a logic board design with the 68040-based Performa/LC 57x series boards, allowing a drop-in logic board upgrade dubbed “Mystic.” For those who don’t mind losing the back cover, the “Takky” upgrade involves installing a logic board from even later Macs, including PowerPCs, but requires some modification.

I chose to leave my Color Classic as close to stock as possible. It came from someone on a Facebook group who had two dead ones he was looking to unload. He sold it to me for $100 shipped, and it arrived yellowed, and covered in stickers and sticker residue, but with almost no damage to the case — and no clock battery leakage. Of course, none of that good news meant it would turn on. Cleaning the logic board and leaving it plugged in for 24 hours resulted in slight signs of life, but I couldn’t get it powered up until I thoroughly bathed the logic board (then thoroughly dried it.) After that, it booted exactly once — then the hard drive failed completely.

Still, that was enough to suggest it was salvageable. The fact that washing the board had an impact meant that the surface mount capacitors were leaking. This being my first experience with SMDs, I watched a solid two hours of YouTube videos covering a variety of techniques for removal, then practiced on a garbage board. I settled on the “snip, twist and pull” approach, to minimize the chance of trace damage. Soldering new ones on was a little more delicate then through-hole caps, but nothing I couldn’t handle. A full set of replacements was done over the course of an afternoon, and after another 8 hours plugged in, some cleaned drive heads, and a carefully built floppy boot disk, it was back to life!

Next came the analog board — the need to be plugged-in for a long time indicated that those caps were at the end of their life too. While getting the analog board out was a pain in the butt, re-capping moved quickly. While I retro-brighted the case back to something closer to it’s original color, I re-capped half the board, and marked the ones I’d replaced, and tested it out. Everything worked, so the next day, I started the second half. With the final set replaced, I re-assembled my Color Classic and was delighted that there was no “charge up” period required — the Mac chimed instantly… then the screen turned a bright white, with lines through it. I yanked the power in terror, took it apart and quadruple checked the rating and polarity on every single capacitor, then re-assembled and tried again. I got the same result, but this time I put the boot disk in — and found that Mac whirred away at the floppy, booting happily. I was puzzled, and felt defeated. Soon afterward, my health took a turn, and the Color Classic ended up left in pieces on my work table for two months…

Not a happy Mac

Finally last week I felt up to re-visiting this project. I found someone willing to sell a replacement analog board, if all else failed, but I was determined to figure out what had gone wrong. I knew everything worked after 2/3rds of the re-capping was done, so at least the potential surface area for error was small. I fired it up again, and watched the slow floppy boot, then set up my multimeter to try to read voltage from some of the ports. As I did, the Mac settled into the desktop and the faintest shadow of the Apple Menu appeared in the top left corner of the screen!

It turns out I hadn’t made an error at all. Some previous owner had cranked the display voltage (probably to try to extend the life of the old capacitors). A careful high-voltage adjustment with a plastic tool, and the picture resolved to something useable. More adjustments were needed, but the Mac was alive — and had been the whole time! All that was left was to find a working hard drive. Most SCSI drives of the era either have failed, or are about to, so I decided to go with a SCSI2SD v5.1. I loaded it into an external enclosure, and after some fiddling in Lido and some back and forth loading some bits from my Mac Plus, the Color Classic was happy. I had to 3D print an adapter to get the SCSI2SD onto the drive tray, but it fits in there solid, and provides more than 4GB of solid state storage.

I found an Farallon PDS network card on eBay, along with a driver floppy, and quickly got the Color Classic onto my AppleTalk network so I could pull some apps and games off my other Macs. I also loaded up a Recovery partition with the System 7.1 installer and necessary System Enabler — since it had been a pain in the butt to find. After a solid 8 hours of burn in, and a few more screen tweaks, this classy Color Classic runs like a dream. A few days later, it found a decent price, and a good home, with an eBay buyer who’d been trying to get a Color Mac of his own for quite some time.

A classic game on a Color Classic Mac in 256 beautiful colors!

Twentieth Anniversary Mac

The Twentieth Anniversary Macintosh (better known as the TAM) is one of the most rare examples of Apple’s legacy hardware design. Conceived of years before the iMac, but by the same designer, the TAM was an expensive limited edition computer, created in Apple’s darkest hours to celebrate their survival to this point. According to legend, Steve Jobs said it represented everything he hated about what Apple had become.

In its initial run, at $7500 USD (over $11k in today’s money) it supposedly included an option for “white glove” delivery, where an Apple employee in a tuxedo, would arrive at your home or office via limo, and set it up for you. Over the course of its short life, the price would be reduced dramatically — but never enough to sell well. As a result, not many of them exist today.

The design is striking — and polarizing — and harkens back to the all-in-one origins of the Macintosh, while leveraging then-modern technology (mostly drawn from their laptop line.) The power supply is external, and encased in a Bose sub-woofer, then connected by a strange locking “umbilical” chord that frequently causes audio issues. The keyboard, and integrated (but removable) trackpad are awful — but aesthetically pleasing, especially when tucked away under the unit, leaving a tiny footprint on your desk.

This effort wasn’t so much as restoration, as a retro-fit. I picked it up for a reasonable (but still expensive) price from a fellow hobbiest one State over, and as advertised, everything worked. The paint is peeling on the top, where a previous owner had apparently attached something with scotch tape, the umbilical is frayed a little, but does not cause the infamous buzz issue, and the impossible-to-find Comm Slot 2 riser adapter is cracked to the point of being basically unusable.

My main use case for the machine was to replace my handy but inglorious bridge machine — a Performa 6200CD. To do this, I would need a working ethernet card. Although I could make the included CS2 card work if I stood on one foot and held my tongue just right, it would fail too easily if the machine moved at all (due to the aforementioned adapter crack.) A dual PCI riser was included, but was not designed for the machine, so had a number of issues that I had to resolve.

Fortunately, the “fat back” expansion cover was included, but the position of a mounted PCI card that aligned with the external bracket left the card resting against the metal hard drive bracket — an electrical short waiting to happen. The same bracket also holds a fan. While I’m not sure the fan is strictly necessary, I decided I would have to create new brackets for both. My, relatively rudimentary, 3D printer skills came in handy, and once I replaced the aging and tiny spinning hard drive with a Compact Flash adapter, the metal components were almost entirely replaced with plastic ones.

Now I could safely mount two PCI cards — but the bracket only has space for one to stick out. While Ethernet was the primary goal, a secondary goal was a USB mouse. I tried hacking at a USB card to modify it to have internal USB connectors, but failed. Removing the metal mounting brackets from the PCI cards, and leaving off the external bracket from the expansion cover allowed me to have two cards installed — but left a gaping ugly hole in the side of my TAM.

Although the shape was unusual, and beyond my 3D design skills to match completely, I did manage to print off a replacement bracket, which I painted a dark gray, that manages to mostly fill the hole, without looking too much of a hack job.

While its technically possible to run OS X on the TAM, with a G3 upgrade card, apparently it carries some risk — and a high cost for the upgrade. Also, OS X doesn’t make a great bridge for really old Macs. Since I have a G4 Cube that can dual boot 9 and X, I decided to leave the TAM at 9.1. I’ll max out the RAM, when I can find some, but otherwise this project is done — and sitting proudly on my desk.

The STL files for my replacement brackets are available here:

Apple IIGS

Launched in 1986, the Apple IIGS is the strangest and most wonderful of the Apple II line — and in many ways the grand finale. The GS is a fascinating machine, heavily influenced by Steve Wozniak. The GS stood for Graphics and Sound, and this machine was well equipped for both as an answer to its contemporaries, the Amiga and Atari ST computers. While the IIGS co-existed with the Macintosh, its older CPU architecture and deliberately reduced clock speed kept it from competing with Apple’s flagship. However, the incredible library of 8-bit Apple II software ran well on the GS, and a decent selection of new 16-bit apps were built to run natively during its life time. The graphical environment that replaced Apple’s ProDOS looked remarkably Mac-like — but in beautiful color at a time when Macs were only black and white.

As well as great games, the IIGS also supported “modern” technology like AppleTalk networking and its easily-accessible internal expansion slots made it easy to expand and update the machine for decades to come. Even now hobbyists are making RAM, storage and maybe soon accelerator add-ons for it.

I got the base unit from a collector in trade for a Mac I had restored, and salvaged a compatible ADB keyboard and mouse from a bin in my basement. I’d have loved to pair it with the original keyboard, but it was just too expensive on eBay. After seeing how bad the picture looked on a modern display (due to the heavy use of dithering tricks they built in to coax a higher resolution out of the ancient tech) I searched long and hard for an original monitor, finally finding one a 3-hour drive away. I lined up a pick-up as part of a business road trip.

I replaced the battery, which had not leaked, and the “magic smoke” RIFA capacitors in the PSU, but found it to be in great condition otherwise, so didn’t perform a full re-capping. Save for the monitor, and metal shielding in the case, disassembly was a piece of cake, and everything brightened up nicely in liquid peroxide and hot water in the sun. Only the power button and adjustment dials on the monitor could not be removed, so retained a yellow look. Once it was serviced, it was time to try out some of those upgrades.

I purchased a 4MB RAM card from Garrett’s Workshop — happy to support another Ohio hobbyist, and a Drive/Turbo CF storage adapter from ReActiveMicro as an internal hard drive. I loaded it up with the fan-made GSOS 6.04 and a bunch of hard drive compatible (or modded-to-be-compatible) apps and games. For compatibility, I found a killer floppy that loads a lightweight GSOS 6.01 onto a RAM Disk and reboots from it.

Probably the most fun was networking the IIGS. I have an AppleTalk/LocalTalk ring around the basement that’s bridged to Ethernet by a Performa. I was able to mount network shares, including one on a Raspberry Pi, network boot, and connect to (but never successfully print to) a LaserWriter-compatible Brother printer.

After two tries, I found a working external floppy on eBay for under $100, and cleaned the heads. The remaining original parts were about $135, and upgrades were another $130, making this an expensive project — but one of my favorites. Break-even calculation is pending, since I traded the complete system to another collector for at Atari Mega ST that needs some love.

You can see a video of this unit in action here.

Apple IIc

The Apple IIc (stylized as //c) was an early attempt at a portable Apple II computer, and actually overlaps the Macintosh, as both were launched in 1984. An incredibly concise design, accessories from first or third parties provided battery power and portable LCD displays, so you could carry the whole thing with you. The IIc is compatible with the huge library of Apple II software, but had a port for a Mac-like mouse.

This is a really elegant machine and had a bit of nostalgia for me. In 1994, my dad was an 8th grade teacher at a missionary school in Germany where we lived for a year, and his classroom had a IIc. It was my first experience with a non-Macintosh Apple computer, and I found it fascinating. I got this unit in exchange for an original Mac I restored as a commission, complete with the cute monochrome green display. It was missing the power supply, and was heavily yellowed, but in functional condition.

I re-capped the motherboard, and found a compatible laptop adapter from an Apple enthusiast on eBay for $20. While disassembling the main unit for cleaning and retro-brighting, I broke a key cap at the stem on the “7” key. This proved to be a disaster — I tried plastic cement, but it ended up jammed in the switch. I searched for months to find a replacement, learning that two different style switches were used in the IIc, depending on when it was built. Finally I found Apple Rescue of Denver who supplied the necessary replacement parts at a not-unreasonable price. De-soldering the old switch and replacing it and the key cap took only a few minutes, leaving the unit complete again. Retro-brighting in a tub of 40v liquid peroxide and hot water left in the sun quickly restored the original color to a crisp “Snow White“.

As part of the trade, I got the official Apple II mouse (only cosmetically different from the Mac mouse I traded). Minor internal adjustments were made to the display, fixing the geometry and brightness, but I did not attempt to change more than a couple capacitors, as the internal design of the CRT was quite tightly packed. I cleaned the heads on the old 5.25″ floppy drive, and added a BMOW A/B Switch to allow the machine to boot from an external drive such as the FloppyEmu. The kids and I played a few hours of Oregon Trail, Carmen San Diego and Moon Patrol, before I listed the completed system for sale. I found a couple boot disks and a relevant manual, and sold the whole thing to an eBay buyer who didn’t respond to any communication, despite getting an amazing deal: $160 plus $40 shipping — which likely got me within a stones-throw of breaking-even on the project.

A video of this unit can be seen here. I remain quite enamored with the svelt little IIc, and have since replaced it with a IIc+ that refined the design.

Macintosh M0001 (128k)

The first in a new line of computers, later called the 128k, but originally just “Macintosh“, this is the computer that really started the revolution in 1984. An appliance-like machine, not intended for tinkerers, but to remain sealed, the Mac project was guided primarily by Steve Jobs. Famously created by a talented team in a remote building flying a pirate flag, this little box really did change the world.

My first commission, this unit came from a sell-off of Syd Bolton’s Ontario, Canada PC Museum after he passed. When I first got it, it would power up, but the floppy drive was missing, and after a couple starts the screen stayed blank and the happy chime wouldn’t play. I started with the usual suspects, re-capping the logic board and re-soldering the flyback transformer, but to no avail. Finally I swapped in my own Mac Plus logic board… and the unit booted right up. Culprit found.

I replaced a few chips on the original logic board but continued to find no signs of life, so after months, finally found a replacement board on eBay for $45. It was sold as original, but turned out to have a (fairly expert) 512k upgrade soldered on. While I waited for it to arrive, it was time for a gentle retro-bright soak in the sun — a little liquid peroxide and a lot of hot water rendered a consistent look everywhere…except the space bar.

After-market 512k upgrade

When the logic board was replaced and the system was stable, I set out to do some burn in… and found the picture deteriorating after an hour or so of run time. A replacement flyback was required, which I pillaged from a parts machine, along with a floppy drive — although I needed to buy a new mounting bracket online for around $20. Finally the machine was happy with extended run time.

I lubricated floppy drive — a little different on the old 400k drives — and cleaned the heads. The client sent a keyboard and mouse he found online. The mouse turned out to be for an Apple IIC, so I traded him for my own spare mouse, and I had a complete, mostly original unit that functioned fully!

Building a boot disk was the next challenge. I have a cache of old System disks from my youth, but I didn’t want to ship those away. With only a single floppy drive, a lot of disk swapping would be in order, so I leveraged my Floppy-Emu and my own restored Mac Plus to set-up a 400k floppy that had a bare System and MacPaint and MacWrite on it, with about 4k to spare.

As you can see in the pictures above, the screen size was initially a little bigger than stock. Adjustment proved difficult, since the pot had crumbled with age. Eventually I managed to shrink it a little with a carefully carved stick (a scary experience that prompted me to buy some plastic adjustment tools!)

The M0001, and the parts machine I drew from each cost me $20, and with parts bought online, the project cost was roughly $115, a solid new cardboard box and shipping cost $100. The client provided an Apple IIc and Apple IIGS, both in need of service, in trade for the commission. Whether or not I came out ahead has yet to be seen…
