I shipped an ASR-32 into NY for a movie shoot and all was going relatively
well until I tried to run a punched tape through. Now wrong characters
are being printed (i.e. C comes out as K, return and linefeed don't work
but instead print characters). Something's stuck/slipped but I have
niether the skill nor time to try to diagnose and repair (though I'm
trying).
If someone in the NY city area has an ASR-32/33 that they can bring down
I'll be sure they get compensated for the time and effort.
Please try calling me at 925/216-0569. If you don't get an answer, call
718/930-8092 and ask for me, and say it's regarding the teletype.
TIA!!

Was it alright before you read the tape after moving the machine? And
does it now malfunction if you type the characters on the keyboard?
Try pulling the reader plug from the back of the call control unit (it's
one of 6,7,8, the other 2 being the keyboard and the distributor disk,
trace the cable to find which is which). IF there;s a short in the
reader, that would elminate it.
Do you know if the problem is on the transmit side or receive side?

Yes, it was working just fine until I attempted to read a tape I had just
punched with it. After that, C would come out as K, carriage return as D,
linefeed as A, etc.

control unit (it's

The reader unit plugs into a module that was installed inside the stand.
At first the reader wasn't working because I had unplugged this (the TTY
has been separated from the stand). After I plugged this in the reader
started to work but the characters were coming out wrong (this is when it
started). Unplugging that module does not fix the problem.

receive side?
I think it's on the transmit side.

Right, this is what I eventually figured out. I didn't realize the reader
cables banched off to different points. Once I found that and unplugged
the cable to the call control unit the problem went away, isolating the
problem to the reader. I then removed the reader and examined it more
closely and saw the tine out of place. How it got that way is beyond me.

Yes... The reader contacts (those operated by what Creed would have
called the 'peckers' :-)) are effectively in parallel with the keyboard
contacts. Both devices give a parallel output, of course. They then link,
via wires in the call control unit, to the distributor disk, which
serialises the data.
The reader has a big solenoid at the bottom that lifts the peckers to
read the tape and then, when it gets de-energised, operates a ratchet to
advance the tape. This is poweed by the PSU in the stand (warning : this
is not isolated from the mains supply!), and is controled by the leaf
contact on top of the transmit shaft. To operate the reader, a little
solenoid there is energised. This releases the clutch lever, causing the
transmit shaft to rotate and turn the distributor bush. That lever also
closes the leaf contact, energising the reader soelnoid. After each
character (rotation of the transmit shaft), the lever is forced forwards
again, and will latch there if the trip solenoid is de-energised (the
reader is turned off). Of coruse as it comes forwared, it opens the leaf
contact, de-energising the reader solenoid and advancing the tape.

That was going to be my guess, actually, but I never post guesses without
some evidence (that is, getting you to do some tests first.

I'm actually more accessible currently on e-mail than by phone so please
e-mail me if you can help.
Thanks!
