Apollo 1240/1260 schematic or solution to red screen on boot

[Ranzbak]

Hi,

I bought a second hand Apollo 1240 accelerator card in non working condition.
At first it produced black screen, but now after cleaning all the contacts I get a red screen.

In order to check the signals and see what is going wrong on the board I would like the schematics.

Any advice on how to remedy the red screen on the Apollo 1240 is welcome as well.

Cheers, Paul

John Hertel know's them backwards. Mine isn't functioning either with a suspect expansion header but here's the traces for battery damage.

Thanks a lot, that at least will help me with that part of the board . Luckily my board does not have a battery anymore, it was removed before it started leaking.

Yeah that's kinda weird. And now in 2023, when there's so many alternatives, you would think it wouldn't be an issue to get info.

I had an Apollo 1240, and 1260, had to sell them as was short in cash when a student. Wish I kept them. They were great.
