Hi!
I receive Radysys PIC-3 4900 arcade/slot machine motherboard based on 486 CPU in "industrial" format.

And with two additional compactflash 64MB cards

Download chipset Radysys R400EX techspecs and will try to reanimate it with conversion to "usual" PC

Sadly all connectors are in propiertal format (except one MOLEX connector). As i understand MS/KBD (10 pin connector is PS/2 mouse/keyboard) can be invistigated by 5V and GND lines. VGA (10 pin connector) can be invistigated by CIRRUS LOGIC standard diagram (all RGB signals already visible and should find other VGA sync and GND signals).
Maybe someone already got the schematics or additional info for connectors or jumpers of such card? And utilities for later reformat of onboard 16MB flash disk and CF cards?
