PDP-11/23-PLUS
PDP-11/23-PLUS housed in a BA11-M with two RL02s, TK50, and third party SCSI drive
Manufacturer:	Digital Equipment Corporation
Year Introduced:	November 1981
Word Size:	16 bit
Physical Address Size:	22 bit
Virtual Address Size:	16 bit
Bus Architecture:	QBUS

The PDP-11/23-PLUS, introduced in November 1981, introduced an integrated solution on a single quad-width QBUS board, which included F-11 CPU, memory management unit, a socket for inserting an KEF11-A floating point unit, and two asynchronous serial lines, which had a maximum speed of 19,200 baud.

The PDP-11/23-PLUS was initially available in a BA11-M mounting box, later on it was sold as the MicroPDP-11 in a BA23 Enclosure.
