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. bill
