Hi
Anyone have any info on an 8" hard drive + 8" floppy combo which
appears to be an "SMS FWD 0101"?
I believe this was used with a qbus system. I don't have the controller
card however, just the box and a 50 pin cable :-)
The floppy looks like 8" double sided. The HD is 8" (been a while since
I've seen one of those).
I'd love to find the mating QBUS controller card.
The large card on top of the hd & floppy appears to have an 2901 and
an 8085 as well as other fun chips.
(I just gotta stop clicking on those blue underlined words ;-)

The odds are there isn't a Q-Bus controller, even though the system
it probably came out of would have had a Q-Bus. Confused yet? :^)
Is the 8" floppy by any chance a "Tandon Model TM848-2E" or "Model
YD-180"? I'm guessing what you have is out of an SMS-1000 PDP-11
based computer. They had their own board for the I/O, and the Q-Bus
plugged into that.
You can find a few pages from the manual (everything I have) at:

That's similar, but not what I have. the backplane and disk assembly
are separate.
There is a very large board connected to the HD & FD, with a 2901 and
8085. This appears to connect to something on the qbus with a 50 pin
cable.

I wonder if that matches the SMS Unibus controller I have.
Quad-wide, P/N FD-1100I, not documented anywhere I can find. One 50-pin
and two 34-pin headers.
Warning - fairly large image:

There are some SMS documents on bitsavers.org that describe your particular
hardware, and also the QBUS interface you are seeking.
