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.
