Macintosh Classic / c. 1991 / now
My dad bought me technology because he wanted me to have a great education and early access to computers. The original Macintosh Classic is gone. This one cannot replace it, but repairing it lets me revisit that gift in a practical way.
“My dad bought me technology. He wanted me to have a great education and access to computers from an early age—I thank him for this, greatly.”
how the right machine emerged
I first bought two SE/30s with a simple idea: keep a compact Mac on my desk, use it, and reconnect with the machines around my early education. One of them now boots happily. But as I pieced the family story together, I realised the computer Dad bought while we lived in Hong Kong was a Macintosh Classic.
That changed the project. A good-looking but faulty Classic in Adelaide stopped being another restoration candidate and became the Dad Mac.
the method / condensed
There are dozens of photos, parts lists and bench notes behind this. The useful version is simpler.
The project became specific when I worked out that Dad's Hong Kong Mac was a Macintosh Classic—not the SE/30 I first remembered it as.
Every connector, board and questionable pad gets documented. Good restoration starts with being able to retrace your own hands.
Schematics, meter readings and help from the compact-Mac community matter more than confidence. C4 taught me that very directly.
The goal is not a sealed display piece. I want it on the desk, booting old software, making things and being touched.
from the bench / June–July 2026
Open the case, discharge carefully, photograph everything and remove the old PRAM battery. Then inspect the logic board for the residue and damage left by ageing electrolytic capacitors.
No power-on heroics. Evidence first.
The old surface-mount capacitors came off, the board was cleaned, and replacements went on in small groups. A lifted C2 pad needed a 30AWG jumper to ground. Weak C3 pads needed patience rather than force.
At C4, my first assumption was wrong. Tracing the schematic and checking it with the 68kMLA community showed the pad belonged to the C72/L10 node—not ground. The correction is part of the story.
By 2 July, every planned logic-board capacitor was physically in place. That is a milestone, not a victory lap: continuity checks, cleanup and system-level testing still matter.
