  you are aware that although there's 2KW of code in
there, it's accessed
 through a 256-byte (128 word) window in Bank 8 which has to be
 programmed via the PCR? 
Yes, thanks.

...
  There are 18 error halts, listed in the BDV11 manual,
which I expect is
 on bitsavers 
The Technical Manual is, but not the User Manual (which may not exist, the TM
doesn't mention one); the TM doesn't cover the software (in the PROMs), just
the hardware.

...
  and on pp107-108 of the PDP-11 Microcomputer
Interfaces Handbook 1980. 
Ah, didn't know that - thanks, that's useful.

It's been a while since I looked at the BDV11 entry there; I was using the
BDV11 entry in the Microcomputer Products Handbook.

...
  The 25 error halts for the 11/23+ are listed on pp
611-613 of the
 Microcomputers and Memories Handbook 1982, and also on pp 47-49 of the
 PDP-11/23-PLUS System Manual (EK-1T23B-OP-001). 
Ditto (useful).

...
  You've already discovered, I imagine, that there
are gazillions of ways
 to set up and use the sockets on a BDV11 
Yup.
