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.

I like them for the many flavors of CPU and and possible configurations.
I have a few

Ok, first hurdle is down. In reading the RQDX3 Controller Module Users
Guide it shows that for a BA23 the 50 pin cable goes down under the Q
bus chassis then loops straight up into the RQDX3. Which is impossible
to do with a modern (hee hee!) 50 pin SCSI ribbon cable as the cable
keys are set
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
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

Hi all!
Re-subscribing to this list after a 20+ year "vacation" while raising
kids. I was pretty active in the Dec pdp10, pdp11, and pdp8 communities
back in the 80's and managed to acquire a lot of "stuff". Now that I
have some time and space again I'm looking back into the pile of "high
