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.
Essential parts that make up a PDP 11/23-PLUS
- M8189 KDF11-B CPU board
 - 22-bit QBUS backplane
