My 11/23+ is in a box labeled PDP-11/23PLUS on the front with
three toggle switches. :-) It has a 9276-A backplane labeled
OPTION 11/23B. It is a 9 slot, Q22 A-B-C-D . That's the home
for my next system which will (hopefully) have 2 meg of memory,
a DEQNA and an Andromeda Card for a small hard disk and 8" floppy.
I also plan on another small 11/23 with 128KW of memory and an
18 bit backplane so I can use the RX02 emulator. And, probably
an Andromeda in there, too
To bring my part of this discussion to an end, I now have a BA23
MicroPDP box with an 11/73 CPU, 4 meg of memory, DHV11 for eight
serial lines (probably only use one to talk to a TU58 emulator
but the DHV11 was just sitting there looking lonely) a DEQNA
and a CMD SCSI Controller set for 6 disks and one tape. Only
thing it lacks at this point is software.
On to my next project.
Thanks for all the help. I had forgotten just how much fun
real computers were compared to PC's and MAC's.

Pete,
Your right the 11/23+ showed up on a lot of boxes but not the BA123
though it would fit. I?m pretty sure you could get the /23+, /53, /73,
/83, and /93 in
either a BA23 or a BA123.? I have an actual badged BA23 pedestal for
my /23+.
I'm fairly certain all microPDP-11/23+ systems were only sold in BA23
boxes, and I think microPDP-11/73 and the later, cheaper, cut-down
11/53 were as well.? But almost all the 11/83 systems I've ever seen
were in BA123 boxes, though they did sell some in BA23 pedestals -
I've got one.
