RL02
Manufacturer: Digital Equipment Corporation


A RL02 cartridge.
RL02 drive.


The RL02 is a 10MiB, single platter, removable cartridge drive introduced in 1978 by Digital Equipment Corporation.

Its 22-bit QBUS controller is the RLV11,RLV12

Its UNIBUS controller is the RL11

Its lower-end cousin is the RL01.

Emulating the RL02

Reinhard Heuberger has created an open source emulator for the RL02 (and RL01) using a Terasic DE0-Nano Altera Cyclone IV FPGA board, extended with necessary interfacing hardware and an SD card slot. The emulator can be used with a real PDP-11, for example.
