I forgot one of the Prime peripherals.. comes from trying to type when falling asleep.. check out all those transposition typos.. This rig had at one time a Printronix P300, and has the cable set up for the Dataproducts interface. I have a P300, tho it is not the one originally with the computer. I had intended the P300 to be used as a line printer with the PDP stuff, but a suitable bribe and/or trade could possibly sway my thinking. Cheers John
