   I don't plan to connect it to a Q-bus system. Even if I wanted to
connect it to a VAX (I don't, see the next paragraph), I would connect it
to a BabyVAX. It's a SCSI device, it would be better off on a native-SCSI
machine like a BabyVAX than on a Q-bus MicroVAX where SCSI is an alien.
   But most probably I won't use it at all, since I already have a Sony
CDU-541 aka DEC RRD42 (1X SCSI-1) and a Sony CDU-561 (2X SCSI-2). Both use
standard caddies. The CDU-541 aka RRD42 doesn't seem to work, but the CDU-
561 works beutifully on my IBM PC AT-compatible with Adaptec 1520A. Yes,
that's an IBM PC running DOS, not a VAX running UNIX, but this is where I
need to read CDs. I don't think that I would ever need to read CDs on a
UNIX box, but in case I do I will have this external RRD40 spare.

   Hmm, I have thought that the numbers for all such manuals start with
"EK", not with "AZ". The standard document sets for such machines normally
consist of a three-ring binder with several documents inside it, and there
is a part number for each document as well as for the whole binder. I
wonder whether the AZ-... numbers that you have mentioned are for separate
docs or for whole binders. If these docs have this structure, could you
tell me all the numbers?

   630QB is in a BA123.

   Again, the same question.
