Hi all, I finally got round to getting my A7000 out to play with and I found the battery has corroded. I've managed to get it cleaned up and replaced the battery. Unfortunately it's not for starting up just get a red screen. I've asked an electronics engineer to have a look at it but he's asking me for a schematic for the board. Does anyone know where I can get a schematic diagram and service manual for an A7000? I'd appreciate any assistance.

I'm not aware of an A7000 manual, but the RiscPC one should be close enough as the CMOS circuit will be similar if not identical.

RiscPC TRM at the bottom of this page:

Oh, Have you tried a CMOS reset on the A7000 (holding down Del until something shows on screen?)

It might also be worth asking on the stardot forums or at least following this recent thread.

Having said that, Chris Whytehead's response in this thread doesn't look promising for anyone looking for manuals.
