You may find that the Versafloppy has an eprom with Z80 code which your 8080
won't like. If you have a Z80A board and 64K of RAM available you need only
figure out what the console for which the code in the EPROM was written would
be. I've got several SD boards, but no FDC, and I really don't know whether
these boards work or not, but I do believe that one popular configuration was
with the SD Sales VDB8024 board, to which one attaches a parallel keyboard. If
your doc's suggest that's what the EPROM supports, perhaps I can help by lending
you that board. I may even have a keyboard that is set up for the VDB8024.

Subject: Versafloppy S-100 board
Today I aquired a SD Sales Versafloppy S-100 bus
floppy
controller. It's currently jumpered to use Shugart SA-800 drives and
includes the full manual with schematics (dated 2/28/78), CP/M I/O
driver source (dated 3/17/78) and a printout of the CBIOS I/O dirvers
version 1.31 for UCSD Pascal (dated 3/21/80). I'd like to eventually
put this to use with my SOL-20. Any suggestions on how best to
proceed?
Thanks
Jeff
