There were actually two S-100 bus extensions on ebay
recently.
There was the one that was stated as such and there was one
that was described as a controller for a floppy drive and drive
( I forget which machine it was stated as being for, SYM1, KIM1
or R65 ).
Hmm... sorry I missed them.
I do have a card that was intended to be used with
the SYM-1 to
drive floppies. When I got it, it was missing the code ROM and
a data bus buffer. I've since located the code but the buffer chip
has been a problem. It is one of those oddball national chips
that can not be easily replaces by a '245 :(
What's the part number? I might be able to help (I have tubes of
8641s, for example).
