Stumbled upon some old photos of 1970s computer equipment today at work (thanks to whoever took the photos all those years ago).

This is a Digital Equipment Corporation declab 11/40 computer system including a laboratory peripheral system and pdp 11/40

BA23 back plane of a Digital PDP 11/23 that I had kicking around the garage for a few years but has now since been given away. This has a massive 64K RAM, six serial ports and two RL02 10MB Disks.

Pavl Zachary's PDP 11/40 display

This is a DEG and is used to control one of the large green Air Traffic Control radar screens.

My friend Zach found this while going through old stuff a few years back. From the date I wasn't yet 13 at the time. BASIC language on a DEC PDP-11/23, I think, which my school had recently purchased.

Zach has said he will send me the whole printout.

I also remember learning FORTRAN on that machine.

pdp11/05 (=pdp11/10)

The paper in Bay City, MI, is still running a PDP11 to handle their classified advertising. Go figure.

This is actually in color, but I scanned it on a B/W scanner :(

Walton RARE playback unit. This uses 2 DAT drives to play back recorded air traffic radar around London Heathrow

An attemt to show that the logo insert is (a) a separate part and (b) is very slightly smaller than the box it fits into.
