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.
