RE: [N8VEM-S100:5218] OT: VCF-MW

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?
