misc boards in with some Amiga stuff

My partner in crime came up with a bunch of (unknown condition) Amiga Zorro boards . . . . Two we couldn't identify: --------------------------------------------------------------------------------------------- PC video card (8 bit ISA), 6.5" long, has RGB VIDEO & COMPUTER VM-1 silk screened in the upper LH corner. Has 5 BNC jacks on backplate, 2 Zilog IC's (Z80 and Z85C300???), and two DIP switch banks (8 ea). Also has a short 10 cond. ribbon cable going to a DB9F on a card bracket. (CGA/EGA monitor??) I'm guessing it may be a CGA/EGA card with BNC outs for the early color monitors..5 jacks --------> R,G,B, H & V sync??? No markings on card bracket. ----------------------------------------------------------------------------------------------- Second card looks like it may be a PC board TBC: Digital Processing Systems 743-750 USX rev 1. Also has MADE IN CANADA. No FCC number to xref. 4 phono (RCA) jacks on the back, and one center off toggle switch, spring loaded. Your guess is as good as mine. Gary Hildebrand ST. JOseph, MO
