DEC PDP-11-34_#2, S/N 4233

This is our second PDP-11/34 system. It was part of the collection that was donated to the RICM by a Robin Katz Banks.
 
The system includes four serial ports and a modem. It has an RK611 disk controller for the RK06/RK07 disk drives. Since the RICM does not have any RK06 or RK07 drives we installed an RL02 disk in the previously empty top peripheral bay.
 
The 11/34 processor cabinet is behind the lower blue sheet metal cover.

The 11/34a contains the following boards:
