    Diagnosing KIM-1 short

    Here's a diagram showing the +5v Caps - there's very little. There's also a Zener wired across +5v in there as a protection for when the incorrect power supply voltage is connected. This can be suspect too - just lift one leg and measure the resistance.

    Any place in the world that might still make Core Memory ? ....I know it's a stretch

I know it's a stretch I've read that the ordinary Ferrite Cores that being sold aren't good enough - as they are the 'Soft' Ferrite Cores. You actually need 'Hard' Ferrite Cores which retain the magnetism, and having...

    Looking for Amiga 1000 Kickstart and Workbench disks

    Looking for Amiga 1000 Kickstart and Workbench disks I somehow misplaced them after being packed up for so long. I'm glad the A1000 still boots up fine, but until I find some disks I'm not sure if the floppy drive is still ok. I wasn't sure if the A1000 version stops at ver1.2 or ver1.3 Dan
