Quad-wide, P/N FD-1100I, not documented anywhere I can find. One 50-pin

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
