Acorn Risc PC 700 Refurb
My friend Steve, who I worked with gave me one of his two Risc PC's… and it was a good one, too:
- Risc PC 700
- 64MB RAM
- 2MB VRAM
- Ethernet module
- StrongARM 200 processor card
- AlephOne DX2-80 second processor card
I hadn't done anything with it, until getting the computer shelving in place, then tried turning it on for the first time.
Sadly it didn't work - although the OSSC and KVM detected a signal from it, I got nothing but a blank, 50Hz video feed and the noise of the original IDE disk spinning up. So I decided to open it up and take a look….
Oh dear. That will be one completely failed battery cell. With nasty battery gunk coming out.
Removing The Battery
First job is to remove the power supply, to get access to remove the battery and get a closer look at the board… it's held in with one screw, into a screw post in the case…
… which disintegrated as soon as I looked at it!
Fortunately the battery was easy to snip off…
… at first glance the board appears relatively unscathed. A quick clean up with some thinners to get the bulk of the nastiness off, and then a little bit of vinegar to neutralise any remaining corrosion from the battery leak
