Hm. I have a Q bus controller for a Diablo 44 which is the 5mb
removable, 5mb fixed using an RL01 type pack. It emulates 4 RK05's. Same
edge connector but only one of them.

Any ideas what this disc controller is?

Can't find much about this on the 'net, other than that it was a
controller
for Diablo/Pertec style drives -- no idea if it's an RK11 clone or
something else entirely. Looks to be suitable for a PDP-11/20 given the
little notch missing from the side there, and the lack of a separate
power
harness for the backplane.

I found one computerworld reference to a distributor stocking them,
MTI. but no hit on the ones I think they are.
I had a friend who worked at a place with this name in Irvine which did
tape and disk controller systems for more than just DEC. He worked @
Microdata on some projects I worked on, then went back (79 or 80) and
stayed there. He had a stake in the company, but he took contracting
work like we had @ Microdata to help out.
The ad I saw was 1981 computer world for MTI, with just the company name.
thanks
