What exactly is a MINC-11, and does anyone need one?

Jerome Fine replies:

The MINC-11 was a box used to provide easy access to a Qbus backplane.
Normally, data acquisition was done with the system, as you suspect. It was
an 18 bit backplane with a number of Qbus slots at one side which held
an 11/23 CPU (usually the dual version M8186), memory, DLV11-J,
and a controller or two. The RX02 controller was normally standard
and the RL01/RL02 controller was also popular. An RXDX1 or RQDX2
could be added as well, but there hardware needed to be adapted to either
the RX50 or the hard drive.

In between the boards mentioned and the BDV11 on the other side was a
number of Qbus slots to hold data acquisition boards. This was a 1979 to
1980 item - I think that would be the time frame. Since the BDV11 boot
roms could not handle an 11/73 (odd address trap), that CPU could not
easily be substituted.

Probably JUST the setting in the power supply.

If you were closer, I would take the RX02 drive.
