.. Just as an update - the Z80 card is coming along well - just a few timing problems to go. Although it boots CPM and behaves correctly, a real softcard diagnostics app would help a lot. If anyone has any CPM or softcard diagnostics, it would be much appreciated to grab a copy to confirm CB's doing the right thing.
I've never seen a diagnostic program, per se. Best bet is try running real applications under various flavors of Microsoft CP/M and Applied Engineering CP/AM.
