DEC PDP-11/83
 
This PDP 11/83, donated by Rigaku USA, is a Qbus based 16 bit minicomputer manufactured by Digital Equipment Corporation.

At the far left is a CDC 9762 SMD Disk. The left cabinet contains a DSD 880-D30 Winchester/Floppy system, and a CDC Model BY3A6-A, Part Number 77015921, 1/2" Tape Drive. The center cabinet holds the CPU with a TK50 tape drive, a BA23-CC Expansion Chassis that holds RD52 and RX50 disks, and two RL02 disks. The right cabinet holds two RL02 disks and a RX02 floppy. There is an additional RL02 drive for this system in the MicroVAX-II cabinet.

The 11/83 chassis contains the following boards:
