I have an M200 and I just had to look up in the docs (on bitsavers) that my unit requires a Hubbel 7484 for the power cable. Yours is different but it's likely to be some sort of Hubbel product. > * Hose from vacuum pump to pickup heel is hardened.

Fortunately, my M200 came with a factory add-on board that's an RS-232 interface to the upstream host. > I wonder where I'm going to find some card stacks for testing it? If I get > that far. An old co-worker buddy of mine gave me a box of his punchcards when he was in school in 1970. He's really on me to read them. I don't want to put his in first and have roller goo or something else ruin them so I have a bit of exploration to do. I'll be interested to hear how your saga unfolds because I'm expecting all of that and more on mine. -ethan
