Hi Paul!
Pleasure to meet you. What kinds of things do you have?
What I would love to do is get the latest versions of RSX11/M+ up and
running. I have compiler licenses for Fortran77 and Cobol81, but only
11/M 4.1 and 4.0 media on RL02/01 packs.

Oh the 9058 is the "Q Bus" card with the 50 pin breakout to 34 pin and
20 pin lines for the various drives. That's not the RQDX3, and I don't
need that since I have the BA23 with a bulkhead connector.
And yes, I do remember nothing could be after a RQDX1 or 2 so they had
to be in the last unus

Interesting, I didn't realize the RQDX series boards didn't use
interrupts or DMA. Does the CPU just poll t
Oh yes. If you could drop David an email with my email I'd appreciate it.

Yup. They're easier to get going for starters and since I got rid of the
11/44 the fastest system I've got.
To go from RQDX3 to any drive you need a distrbution panel as used in
BA23 or M9058 distribution board usually used in BA123.
Yup, got one of

Re-subscribing to this list after a 20+ year "vacation" while raising
