I can't help from personal experience (my ASR-35 from N.J. hasn't made it
home yet - it went from The Armory to Canada and should be in Ohio by
the end of the month), but I can make the suggestion that it sounds
like a dirty contact in the output rotor or a broken/disconnected
lever under the keyboard. Looks like you are missing 2**3 in your
parallel->serial conversion, but I couldn't guess at what stage.
I do not own nor am I expecting any ASR-35 manuals. Perhaps the
Greenkeys list mentioned elsewhere might be useful to you for securing
a set of docs. I'll have to be hitting them myself when my 35 shows
up. I'm certain it's in need of a PM cleaning and lube, and I have *no*
idea how to do it at the moment. (The TTY itself still has strapping
tape on the carriage and protective film on the cover - except for a
test sheet, it looks virtually new. Still needs a lube job, though).

Time to part with my 7978 9track reel-to-reel drive. Appears to have
power supply problem with both motor drive and logic PSU's - fans
function on power up but nothing else. Unfortunately I have not had the
time/space/expertise to get to grips with repairing this so can't offer
much more insight I'm afraid. Free to anyone who can physically remove
it from me in Central London (really needs 2-3 people to carry it).

Hi
I've only fiddle with my ASR33. You need to find out what
is wrong first.
As an example, my ASR33 takes the output of the keyboard
and passes that to the distributor at the back of the machine
to serialize. The parallel output of the keyboard depends
on a bunch of switches that are located at the side of the
keyboard. These switches are exposed to all the gunk that
usually floats around in a teletype. I'm sure you may find
that one of the switches is dirty and just needs cleaning.
Until the signal is serialized, the problem can be anywhere
>from the switch on the keyboard to the brush on the distributor.
This includes the connectors. Some tracing with an ohm meter
( power off ) will most likely find the problem.

The A11 light dosn't function due tyo a blown 7405 chip in the front panel. I have had to replace several of these myself on my altair and on my IMSAI. 7406 seems to make a better replacement as it can take higher voltages
FWIW,
The GA-16/220 is a computer that is used in the Excellon CNC-4 ,
CNC-5 , and CNC-6 consoles. These consoles controlled the
Excellon Drilling/Routing Machines.
www.excellon.com for more info.
My most favorite was the AT&T 5620 with a host running layers. Even without
layers, the 800x1024 page-sized screen was nice. Second would be a Tek
4207...fun graphics. Favorite "normal" terminal would be an amber phospor
VT420.

I dunno, I prefer TIFFs, but they have the disadvantage of being honkin'
huge.. But at least I can go and in be anal-retentive and edit them to look
better than the originals, can't edit pdfs nearly as much...

Hi Stefan:
You may be interested in the greenkeys teletype email list -- lots of good
folks with questions, answers, etc. (I am admin of it). Let me know if you
want more info. You could join and ask, or I could forward your message if
you'd rather. There is likely someone on greenkeys who can help you.
I'm not personally familiar with the 35 (though it's just an ascii version
of the baudot 28). The 35 is a heavy-duty machine that you should be able
to return to service (as opposed to the 33, which is a crappy design that
just wears out). I'd love to see some pics of your 35.
There was a guy in NJ last month with two 35 machines on ebay. He could
not get $5 for them, and may still have them.
I have collected a few teletype machines that I am restoring (not selling):
an M15-ksr, an M31-ksr, an M33-asr, an M28-ksr table-top, an M28-ro, an
M28-rotr, an M28-td, an M14-td, and an M14-ktr.

I would doubt AT&T handles support for a 3400, since it is an MP-RAS
machine, and I *know* NCR retained MP-RAS... I'm fairly certain that I saw
System 3400 docs on NCRs website when I was looking for Tower manuals..

I recall someone asking about SIPPs the other day. Was it on this list ?
I found 3x 30 pin SIMM -> SIPP converters in my junk box if that is
out any help.
