Data General's full-size Novas and Eclipse series machines use two of the same 100 pin connectors found on S-100. Many of the slots are keyed to accept only certain types of cards, but they're more or less wired alike. The CPU for example can only be inserted in the bottom-most slot on a 1200, with either memory or a CPU feature expansion card directly above that. An 800 splits the CPU cards between the two bottom slots. I can't speak to the backplane design of the Eclipse series or the later Novas, but it wouldn't surprise me if they're similarly keyed. -Alexander 'Z' Pierson>This is just one vendor. There is something visually similar with Data General Nova systems but I'm not experienced enough to comment on them.
