PDP = Programmed Data Processor. It was a ploy to tame down the idea of
large, expensive and complex computers.

The PDP-8E/F/M/A series was quite popular swith sales in the many tens
of thousands. There are many of these in service as machine tool
controllers and other uses. PDP-11 series was even more prolific.

Rare machines are the PDP-1 (few left), PDP-5 the forunner to the 8, and
10s. The total sales for the PDP-1/4/5/6/7/9/10/12/15 combined was under
5000 units. Generally the 18 and 36bit machines are tough to find and if
found represent a bit of work to run.
