So I finally got the Micro PDP11/53 hooked-up to a terminal. When back at the folks at
over Christmas I found an old MMJ cable and DB25F adapter, which work when the latter is
plugged into the VT. I need to try the MMJ cable I bought recently with this adapter, but
suspect it is something about using an MMJ direct between the PDP and VT. ISTR having this
problem before trying to direct cable a MicroVAX to a VT's MMJ port.
In any case, I'd like to join this machine into Hecnet, hope to run RSTS/E and have a
couple of questions:
- Looks like only v7 of RSTS/E is available, would this suffice?
- Would anyone be willing to help me out with media (happy to cover cost for media and
postage, of course)?
Regards,
Andrew

I had to check some history for this... the Wikipedia article on RSTS/E
is helpful.
What would you use for a DECnet interface? V7.0 is DECnet Phase II.
Phase III was added in V7.1, but that's still iffy with HECnet, and
you'd need a sync DDCMP interface (for a Q-bus system like that it would
be a DMV11). More to the point, it looks like the Micro-PDP11 support
appeared in V8.0, and I suspect there may be some other small details
specific to the 11/53 that are later still.
For Ethernet (DECnet Phase IV) you'd need V9.3 or later. I don't know
about availability of late releases like that...

Right, so I'd need to plumb the 11/53 into say an Alpha via a serial
connection. Sync... so I'd need to get a PCI sync card too, for the latter.
Ugh.

Right...
Thanks for the info!
