PDP-11/34 decdatasystem

Home » PDP-11/34 decdatasystem

In my collection I have a blue-and-white “decdatasystem” consisting of a TU10W drive and an RK07 drive.

I decided to investigate these a little further last weekend, and unexpectedly found that below the TU10W is an entire PDP-11/34 chassis with programmers panel and interfaces for the TU10W and RK07.

Here are some pictures.
