I have a quad Qbus board in front of me. It is labeld "System Industries
9901-6082-A". It has two 40 pin IDC connectors, lots of TTL, four
AMD2905, three EPROMs, the usual PALs, ...

This is some sort of disk controler according to google. What I didn't
find out: Is this the complete controler or is this only a part of a
controler? There is a "System Industries 9900". It is a separate 19"
rack box containing a SMD (?) controler. It is interfaced to SBI or
UniBus or ??? with a bus interface card and ribbon cables. Maybe the
card I have is the QBus interface card?
