WTB: DEC PC04 Paper Tape Reader/Punch

It is, that's why it's the PC8E (fits the Omnibus of the PDP8/e, amongst others). The unibus controller is an PC11 (I forget the M-number). But the pumch/reader for that is a PC05, and contains rather more electronics than a PC04. It's possible to turn a PC05 into a PC04 by removing some of the flip-chip cards (including the 3 'specials', addiong an M113 (I think) and doing a bit of wire-wrapping. I did this, having got a PC05, an PC8E interface, plenty of other Unibus paper tape readers and interfaces but no other paper tape system for the PDP8/e. What machine does the OP want to use it with? Going o nthe 'minimum number of errors to make it consistent', I assumed he simply meant Omibus rahter than Unibus, and wants the PDP8/e compatible one. -tony
