the battery on the workstation board needs replacing. the old battery has failed and the board has reset to factory settings. it would appear that your machine has an lcd screen and there are bios settings that need changing for the screen to work. so remove the workstation board ( it is the board on the left hand side of the control - the big silver box in the cabinet) replace the battery - a cr2032 battery- take note of the workstation board part number off the white label on the bottom of the frame (3-424-****) which if you send them to me i will send you the bios settings.
replace the board and install a ps2 keyboard into the furthest ps2 port on top of the board. you can then fire it up and alter the settings.
my e-mail (for the next 2-3 weeks) is firstname.lastname@example.org.
ps if larry from patriot is watching please drop me a line
