MicroPDP-11
In the second half of 1982 the MicroPDP-11 replaced the PDP-11/23-PLUS; the most important advance was the new BA23 Enclosure with its coordinated components:
- H7864 Power Supply
- H9278 Backplane
- Two 5.25" full height bays for mass storage devices
- RQDX1 MFM Disk & Floppy QBUS Controller
- RX50 dual-diskette drive
- RD51 MFM Disk drive
The older BA11-S enclosure was offered for a while in parallel with the new BA23, but its production was finally discontinued in 1983.
The M8189 KDF11-B CPU board was still the same as in the former PDP-11/23-PLUS.
This was the start of a new series of DEC PDP-11 and VAX QBUS-based "Microsystems", beginning with the first member, the MicroPDP-11, which was later renamed to MicroPDP-11/23 to distinguish it from its successor systems.
