Hi Doc,
I have a pair of SI 9900 controllers that I THINK will work with
your QBus board. They are rack mount drawers about 4" high with
boards and stuff in them. I believe they are complete, they were
closed with the screws installed, but I don't have an interface
card for them.
Actually, I may have a pair of QBus cards that will drive them,
but they are connected to another pair of SI boxes with
controllers inside. I also have documentation for the QDA50E
which I believe to be the QBus version of the 9900 and software
drivers and formatters on TK50 for the same.
If you are interested in these, let me know, and I'll figure out
the shipping (or you can pick them up next time you come through
Denver).
Regards,
Clint

There are other components, but maybe that's enough.
I can't find any reference at all online. Does anyone have a clue?
