Re: Non-working Commodore PET 3016
Well, colour me shocked. I would never have expected PET keyboards to have been made using anything but discrete switches.
Anyway, if you are getting keypresses misinterpreted consistently as neighbouring keys, that is almost certainly an indication of a multi-way connector being displaced by one pin (the keyboard is scanned as a matrix of switches; one of the "row" lines at a time is pulled low, and any key depressed in that row pulls its "column" line low. Note that rows and columns here probably do not correspond exactly with the rows and columns of the keyboard); so check all wiring carefully.
