[GreenKeys] 35 ASR Basic Help Request

[Nick England]

Strategic advice.
First, Read. Read. And read some more. Read the description and principles
of operation.
Learn how the keyboard and typing units are *supposed* to work and then
figure out what isn’t working in your 35 ASR. Take the covers off so you
can see what is happening. On a 28 ASR you can remove the entire keyboard
and base from the cabinet and operate it on the workbench. I don’t know
about the 35ASR.

You are lucky in that it almost works. The keyboard is keying and the
printer is printing.
Look at the codes for the character you are pressing and the character you
are printing. One or more bits are stuck, either in the keyboard or in the
printer. Often this is merely dirt and old gunk keeping a code bar from
sliding. Look at the codes and figure out how to exercise one bit at a
time.

Carriage return. Does Local CR work? If so, then it is just the stuck bit
causing your problem between keyboard and typing unit.

You’ll need to figure out how to turn the motor by hand while keeping loop
current on so you can cycle the machine in slow motion.

Good luck and enjoy the learning experience. These are fascinating machines
and you’ll be enormously pleased when you understand a problem and fix it.
