They'll work with the processor; they'll work with the the 3rd-party disk
so long as it emulates an RX50 with MSCP protocol.

I have the same set (and a lot of other XXDP/XXDP+ files), and I have
listings and notes from DEC maintenance courses.

There were some manuals on microfiche; I have course notes on paper for
XXDP/XXDP+ and my own notes for XXDP Version 2 (I think that's what it was
called; some people referred to it as XXDP++ but that wasn't what DEC
called it) as on those disks.

There's a key to the names. For the older versions:

Hxmnrp.SYS is a system file: H means SYSTEM, x=M,D,U,S,Q for Monitor,
Decice Driver, Utility, Supervisor, or miscellaneous ; mn is the device
mnemonic for the medium supported; rp is the revision and patch level.

tmnirp.BI? is a diagnostic program;
  t processor type, eg V or Z
  mn device mnemonic, eg RQ
  i program identifier, eg C
  rp revision and patch level, eg B2
  ? is N or C (BIN=binary, BIC=relocatable binary)
Thus ZRQCH0.BIC is for any processor, using an RQDX controller, third
diagnostic of the set (this one happens to be a disk formatter, but you
would only know that if you knew what was in the set), eight version, never
patched.

There are some special mnemonics:
  DI directory utility
  SU setup utility
  AA XXDP supervisor file
  AB PT/AMS supervisor file
  SA User manual
Apart from that, most of the mnemonics are simliar to the letters of the
device name (eg RQ for RQDX, MR for MR11/MRV11, DL for DL11/DLV11, etc) but
usually not the standard DEC device driver mnemonics.

Dtirp.BIN is a Unibus test; t is the test type, rest as above, except
  0 instruction test
  1 adressing test
  6 AA11/VT06/LAB11 test
  8 Unibus test

The common processor type letters for QBus are
  J 11/23, 11/24
  V 11/03
  Z any processor

If I can find the source files, I'll put machine-readable notes on my web
pages (probablyt as PostScript). That is mostly XXDP V2 stuff. I *might*
have some machine-readble XXDP+ notes; if I can find any I put them up too.
 I'll post a note to the list if and when...
