MSCP Qbus port layer doc sought
I'm starting to pick up my KA630 emulator again. In particular, I want
to give it MSCP disk.
I have various MSCP documentation files, but they talk about MSCP
proper. None of them describe the Q-bus - nor even Unibus - port
drivers in enough detail for me to write an emulator; most of them
barely mention either Q-bus or Unibus.
I find I wrote a bunch of code, and I'm fairly sure it was based on a
doc file, but I cannot now find that doc file. And I find the code
disagrees with NetBSD's MSCP support. I tried to use the NetBSD driver
as documentation but end up with the response ring doing unexpected
So, I'm looking for the Qbus port specification. One of the text files
I found on bitsavers (a DEC-internal TMSCP document) says "See
UNIBUS/QBUS Storage Systems Port Specification for additional detail".
I also found a message to a simh mailing list, quoting an RQDX3
document which, in its "Applicable Documents" list, has
o UQSSP (Unibus/Qbus Storage Systems Port Specification)
Those sound like what I want.
Anyone happen to know where I might be able to find such a thing?
