I think I've got one of those. 2708 EPROM on
board? I made an
adapter to go from the front-panel DIP socket to the molex connector
used by the MITS Altair.
Was it really the first one?

They were called SD Sales at the time they produced the first Z80 kit.
They were real prowd of makeing the first S100 Z80 Card that work and
ran a few adds anounceing it, in Byte & DrDobs that would have been in late 77 early
78.
They then came out with a full line of cards and 2 complete systems in 1979..1980
under the SD Systems name.
They were on the North East side of Dallas TX in late 1979 when I flew out to talk with
them about a
dealorship.
As I recal they got into Loto machines and went out of business, but I may be mistaken.
I did not keep track of them after about 1981..1982.
