[vcf-midatlantic] jade z80 cpu card

Quick show of hands....anyone have a working Jade Z80 CPU card that they use? Are these nice worth working to restore? I got one that came with a California Computer Systems S-100 computer. 8 years ago I tested it with an in-circuit emulator that seemed to indicate it was at least able to initiaize but I have not gotten it to talk nicely to an I/O card, garbles characters. I dropped the project to move onto something else. Thinking of returning to it to see if I could make more progress. BIll
