Hi Mark,
How many S-100 boards do you have plugged into the Super ELF? I have a small 4 slot S-100 mother board that came with my Super ELF (needs sockets). But I have no idea how it is supposed to connect to the Super ELF? Are you expected to bridge wires to it via the solder side? Where did you get a copy of Quest Full Basic, at some point Matt would like to put that on his EPROM board, I would like to help sort that out. PS. Wow, that's a lot of sockets! Did you do all the 2102 RAM chips on the Expansion Board?
