I posted it last night. If you've not got it I'll e-mail it to you
privately.

The machine will run without that memory card - there's 64K on the system
board, and the memory card is another 64K bringing the total to 128K

It contains only standard devices (64K*1 DRAMs and some TTL chips) so in
theory you could make one from the schematics in the Techref. You might
find one somewhere, though.
