compact mac

Hi all, I'm restoring a 128k with a Levco Monster Mac board in it. I cleaned everything up, serviced the floppy, and replaced a burnt plug on the analog board, along with a burnt Rifa cap. Everything seems to work but I'm getting these weird staticky artifacts on the screen. Has anyone seen...

Hi there. Are there any guides, instructions and component lists available for purchasing a small fan for installation into the rear of the Plus chassis? I've seen various custom mods but nothing a novice can immediately follow.

I have been questing for a SE/30 for many years. I now have one, and have been looking around online and see the incredible skills being put to good use with ROM swaps. Recapping the motherboard to making upgrade cards (last I checked, that was the realm of Big Tech). I would really appreciate...

I purchased this Mac 128k logic board knowing it wasn't working. I've poked at it a little over the last 6 months, which includes: Building a 4164 DRAM tester and testing the original DRAM. I found 2 were faulty but ended up replacing them all. Swapping the LS166 @ F14 & F15 (example board...
