Doug Scott of Arrow Plastics' composite vintage label printer is made up of bits including a 1993 Maxtor RD54 hard disk, a DEC PDP11/83 and the case and serial cards from a 11/73 - "the oldest bits in the box, which go back to about 1987."

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.
