Re: Stubborn A5000 - no video

I have a A5000 board that won't boot with battery damage and also what looks like electrolytic cap damage from the SMT ones, looking at the pic looks like a sort of trickily substance there not quite battery damage. Have a look at the cap's.

Re: A7000 single slot backplane. New batch.

I would be interested in one, what would be realy useful too would be the addition of the RTC clock chip with a 2032 coin cell on as most A7000's are ravaged with battery acid, which usually takes out this and the IDE data lines, floppy usually survives as routed a different away from the zone of do...

Re: Replica Atom

The Lee Smith Case would be one way to provide a modular case for those that want a case and have a 3D Printer, which could fit different keyboards with the look and size of the Atom.

Re: RiscPC/Archimedes Monitor recommendations?

Holding a numeric keypad key during power-up changes the monitor type to that value - a quick and easy way to get an Arc to deal with a monitor when you can't see what's going on.

Re: My first Atom....

The best start is indeed minimum configuration. Then take out the IC's one by one and clean the IC legs and socket before putting it back. Next step is to check if the +5V is available on the IC's and eg pin 1 and 31 op PL6/7. Also switching the 2114's will help if one is broken. Is your Atom still...
