New MV-II boots! And, of course, Questions....

  I'm quite tickled. Also inordinately proud of myself (for figuring
out the BA23's slightly different connections & stuff and not letting
loose any Magic Smoke).
  First thing:

  Thanks, Terry! I really like it.

  Terry's rackmount MicroVAX II has been condensed into a single
BA23. For the nonce, I'm running a single RD54 and a TK50 on their
respective controllers, and a DELQA ethernet board. The KA655-A with
32M is a LOT faster than the KA630 with 13M. The TK50 is slow as
ever....
  I was hoping the BA23 would be quieter than the BA123. It's not.

  Questions:
  Does the KA655 CPU make this a MV-3800, a MV-III, or a MV-II with a
KA655?
  Terry, looks like you were right:
  The memory board, which is a DataRAM 63016 C0. Listed online as a 16M
board some places and 32M others. The system sees it as 2 16M boards.
Is this kosher?
  The 3-position CPU-RAM ribbon cable is plugged at one end and at the
middle connector. Does it matter?
  I'd _really_ like to run the RX50 instead of the TK50. Unfortunately,
I don't have a cable. Can a PC floppy cable be modified to work? It
looks like, from reading past posts, connecting on the "B" connector -
i.e. no twist - ought to do the trick. Not quite brave enough to just
plug it in and see.
  Last (not really applicable in the BA23), I see references to
terminating the last RD5x on an RQDX3. Is that termination effected at
the distribution board (M9058 in the BA123) or on the drive? Drive 1
and Drive 2 don't look any different. Which may be why they're, um,
terminally off-line.

        Doc

P.S. - I've always wanted to say "For the nonce"....
