Taking a RISC on some A7000s

I bought a job lot of three Acorn A7000 computers from eBay, all in various states of disrepair. The pictures on the auction weren’t that clear, so I was taking a bit of a gamble on what sort of condition these were going to be in. So far, it’s been a fairly bitter-sweet haul of goodies.

The best condition of the lot was the first one, which came without a power supply, drives or RAM, very bare bones. The motherboard on this one is in very good nick, with a minimum of corrosion damage, which is so common in these computers.

The second one comes with a power supply, floppy drive and motherboard. Again, the RAM, hard drive and CD-ROM drive were not included. This one doesn’t have a CMOS battery in it at all, and had a few dabs of hot glue in places. I tried to boot this one up, however so far I haven’t had any joy with it; there’s no beep when you power it on, although the monitor does respond (albeit with an “out of range” error).

The third one was a pleasant surprise, in that it was an Acorn A7000+ rather than a A7000. This one came complete, with RAM and a hard drive. The only problem is, the motherboard is badly damaged by corrosion. I’m going to try giving it a bit of spruce up with some contact cleaner and pray that none of the tracks have been damaged. Sadly, however, I don’t think that’s the case.

I’m confident that I can get at least one working A7000 out of this bundle.
