And which of those manuals covers the punch mechanism? Did you bother to read any of them before flaming? The OP is right, the punch mechanism is not DEC. I believe it was Roytron. There are some Roytron manuals on bitsavers, the punch shown there looks like the mechanism in my PC04/05 but I can't be sure, there may be subtle differences. But those might be worth a look. -tony
