Well, I’ve got 2 Amiga 3000’s going, which means they are in 30 pieces on my workbench.
One is a A3000D, with 2MB/16MB/256MB of various RAM types. I’ve managed to get the latest custom chips on the mother board, all but a Super DMAC04. This machine has been in the basement for a while, with battery damage and a few blown caps. It now boots with 3.1 KS and 3.9 OS. The VGA port takes a little while to warm up, the machine needs to be on for about 2 minutes and then power cycled to get VGA back up. Working out the VGA is the next major task…
Number Two, is an A3000T. I can’t think of a heavier computer. This one booted right off the bat, but for some reason the mouse and keyboard wasn’t working. Scouring the motherboard for bad components/traces, reading forums and voltmeter came up empty. I could understand why one port would go or just the keyboard… but all three ports? The system would boot to a temp OS disk I mounted, but as soon as the OS was up (or even the KS screen) not keyboard or mouse action. Weird. Even the 3 finger salute on the KS screen..
There is something to be said for computers with a keyhole embedded in its face plate. Yes, when in the locked position — no keyboard or mouse. Funny… I have never had this happen in the last 30 years. The trick that works on old bike locks (Plastic Bik pens, cut in particular way) works on the lock in A3000T. I can see that the lock has been man handled before. When I opened the lock, everything started working.
This machine needs a lot of TLC. The case wasn’t intact, missing the front and top sections. It also has older chips than my A3000D. I was kind of hoping this one was going to have a late revision Super DMAC… oh well 🙂
