[pups] Suitable PDP11s, in the UK

[Robert Tillyard]

Sorry my previous message seemed to be missing the text that I wanted  
to send... see below...

I have what I believe is a PDP 11/23 in a cabinet with two RL02  
drives. I rescued it from a company who were just going to skip it in  
the 90's. I've never used it and don't have an OS for it but the  
company had been using it up until the day the that I rescued it.

The machine is located in Bury St. Edmunds in Suffolk. If someone can  
put this to good use then they can have it. I'll post a picture of it  
up somewhere tonight to help identify it. I think it may have some  
schematics with it as well.

Regards, Rob.
