I suppose I should thank YouTube’s recommendation algorithm for getting this started. Sometime in 2018, I ran across several vintage computer repair videos that got me thinking about the great computers of the past. The videos both scratched a nostalgic itch and fed a need. I’d been looking for a hobby to get my mind off the daily grind, but I couldn’t think of anything that didn’t feel silly or uninteresting. Then I saw YouTubers explaining and repairing computers I’d spent countless hours hunched over in my youth along with many others I only saw in magazines.
As these things go, a few videos turned into a series of weekend binges, and before I knew it, I was on eBay bidding on a vintage Mac. But not just any Mac; it was an SE/30. The best of the compact Macs, and an inconspicuous powerhouse in its day.
I bought my nicely maintained Mac from a seller in New Hampshire. It came with the keyboard, mouse, Kensington trackball, original disks and manuals, dust covers, and a carrying bag. I paid the healthy sum of $311, but it was in good condition, and I was proud to own such a classic machine.
When the computer arrived, I fired it up and heard the once-familiar chime of a happy Mac. Even more nostalgic was the whirring of the Sony 3.5-inch floppy drive and the distinctive sound of its eject motor. Unfortunately, the hard drive did not work, but the computer seemed fine otherwise. Until… I turned it off and on a few times. Before long the screen would fill with random lines and the Mac stopped making sounds.
After some Google searches, I soon learned the dangers of leaking capacitors. If you want to own vintage computers you should be willing to repair them. So, a hobby was born.
Before I could fix my little Mac, I had to learn how. Many hours were spent watching YouTube, reading websites, scanning forums, and selecting tools. Soon, I had a true hobby: something that occupied my time and took my money.
Over several months, I built a good electronics workbench. This was certainly overkill for repairing a single Macintosh, but I was bit by the retro computing bug, and I was going all in.
With the help of my new tools and several YouTube tutorials, I successfully heated and pulled each of the surface mount capacitors, extracted two through-hole capacitors, cleaned the board with white vinegar (where needed) and isopropyl alcohol. I then replaced each of the capacitors, improving my soldering skills along the way.
With the logic board completed, it was time to upgrade the stock RAM from 4 to 8MB, scrub all the Mac’s nooks and crannies, clean and lubricate the floppy drive, and address the dead 80MB hard drive. The drive showed no signs of life. While I measured voltage on the drive’s circuit board, the drive motor was a stone. I have learned that rubber parts within vintage Quantum drives can break down and cause the head to stick, but it seemed to me the drive motor had totally failed. Being new at this, I badly stripped a screw trying to access the internal drive mechanism, so it was time to try something else.
I appreciate the benefits of solid state storage over degenerating magnetic media, so I pursued replacing the original SCSI drive with an solid state solution. After some research, I secured version 5.1 of Inertial Computing’s SCSI2SD. Once in hand, I was very thankful for a wonderful setup guide available at David and Steve’s Blog. This site also provided starter image files to load onto the 2GB SD card I had purchased for the Mac.
Once the drive image was loaded, I was ready to test the SE/30. After a quick prayer and double checking the cables, I powered it up and was greeted with a happy Mac and a booting drive.
With the parts lying on my bench, I noticed the SCSI2SD was roughly the same size as the hard drive’s circuit board. After some measuring, a few trips to the hardware store, and good use of a Dremel tool, I fashioned a metal plate for mounting the SCSI2SD to the Quantum hard drive.
It took some work getting the modified drive properly aligned in the mounting cage, but with my sleeper SCSI2SD in place, the Mac was ready to be buttoned up.
Once back in one piece, I utilized the incredibly useful Floppy Emu through the external floppy connector to load a complete operating system and several useful apps. For the OS, I debated whether to go with the original System 6 disks that accompanied the computer, move up to System 7.1, or jump all the way to System 7.5.5. After taking all three systems for a spin, I decided System 7.1 provided the best experience. It could run System 7 programs, but was slimmer than 7.5.5.
In a stroke of luck, I completed this restoration on September 15, 2019. Almost exactly one year from the date I won the eBay auction. During that year, I learned new skills, built a workbench, and discovered a hobby. I’ll always be thankful to the Mac SE/30 for this great experience.
