Don't know if anyone can help on this, but wanted to post this query to the kind folks here... I have a PDP-8E system, but it appears that the previous owner got many of the parts from different sources. The system has a paper tape reader/punch, but it's for a PDP-11 (PC05) not for a PDP-8 (PC04). I have some information that shows how to convert a PC05 into a PC04 so I can use it with the 8E, but I would prefer to not have to do the conversion unless absolutely necessary (I don't like to mess with historical accuracy if at all possible). So - does anyone have a working PC04 paper tape reader/punch that they would want to trade for a working PC05 paper tape reader/punch? Thanks mucho! Jay West
