[TUHS] weird problem with our Decwriter III terminal

[John Chung]

I would start with the gears first. Stepper motor
testing can be done by visual inpection by running
through 1 character at a time. Mark each turn when
moving to the next character. This requires diassembly
of the casing and other visual blocking components.
