He also swapped some of the guts from the monitor of a later PET 2001 (keyboard style) into our chicklet-style 2001 monitor -- I'll let him elaborate on what exactly those guts involved. Then he worked on the chicklet PET's cassette drive; he said the mechanical parts are good (needs a new belt) and he'll spend time on its electronics another day. Meanwhile he taught me how to fix the non-responsive orange buttons on an Apple // joystick (mostly just open the joystick, dip the buttons in alcohol, press them a zillion times).
I replaced a burned out resistor in the monitor circuit board. We wanted to figure out why it was being burned out but we could not locate a replacement for the TIP29 transistor that we suspected was bad/the cause pulling down the resistor. Makes sense to replace the entire monitor, but it'll be green not blue text. Next workshop someone may want to bring a TIP29 or equiv. to continue with the repairs. b
