Unit is in working order, although at this time we do not have an appropriate XT keyboard or DOS boot floppy.
Progress! Found a keyboard, some work on the floppy drive, found DOS 4.01 boot disk, and found documentation for the video card. The video card is capable of both mono and CGA, with the right combination of dip switches on the card and motherboard, we are fully functional with color graphics.
