Re: 9100 Video display

The video card can output B/W or color, this is set by the jumpers on the
vidocard itself. Grab the service manual and look at the schem for the video
card to work out what the jumpers should be (i haven't made a note of this
unfortunately) but its obvious from the schems.

I've seen docs that say the video is 'IBM CGA compatible'... it is true that
it is low-res 15hz, it has seperate syncs, and they're inverted, so invert
them then combine them in order to run it on an arcade monitor...

I have tested working 30pin 1MB RAM simms if you want to beef yours up, one
assumes you can give it 8mb ram with the right dip settings... 9100's only
have 4 slots, and 4mb max ram.
