For Marchintosh I dug out this nice black Performa 5400/180 (not DE actually) from the cardboard box it was in the last 10 years or so for a quick checkup…
It seems I actually never opened it, and I broke a clip from the backplate cover, and some of the melted bits holding the shield, which isn't unexpected. Some UHU Plast later, it's all back on as new.
It still boots, although I probably should make a clean install someday. The CD caddy makes some noise.
And the battery was still there… I definitely never opened it before. The battery is really empty! But it didn't leak. I already cut open another one btw, I could probably stuff a CR2032 in there for a more original look.
Now, looking at this monstrous fake PCB edge connector (why did they go such lengths to fake an edge connector from plastic?) (Discussions on Discord suggests this might be to avoid having to gold-plate the whole logic board)…
It seems it has the same thickness as usual PCBs, and pin spacing of 1.27mm, and 3.96 for the power section, so it should be possible to make a connector for it from existing parts.Like, slicing a PCI connector… Although I found some other ones that might be simpler to use, but I'll have to order them.
A quick try in KiCAD of what a test harness for those might look like:
At least the pinout is partially known already. Anyone has other sources to complete it?
