Hey guys,
Further to our conversation - I was looking at this beast:
http://www.ebay.com/itm/Teletype-equipment-1-model-28-writer-1-reperforater-
1-50vdc-supply-etc-/121791042544?hash=item1c5b4fd3f0:g:UR8AAOSwnDZUJHWs
Wasn't sure if it was two units? The first couple of pics look different.
Anyway, if I understood correctly, it was possible (and possibly done in the
1970s by hobbyists) to convert one of these baudot teletypes to ASCII and
use with a computer? This one is out of my reach since the auction is pick
up only. But I kind of like the look of the Model 28 and I understand
they're pretty bulletproof once you have them working. I'm just not sure if
this would work, and if this particular one is ASR or what, because it
mentions a reperforator and from what I read 28s that came with that had a
tape reader also?

I seem to remember that the Tech Processor Technologies 3P+S described how
to get a model 28 running with its IO board. You'd have to check that, but
sure why not? It's just harder to do anything with a machine that's not
really made for systems that generally-speaking look for ascii and 8 bit
tape to read in programs.

Thanks! I'm just trying to figure out my options. There aren't many teletypes
coming up to begin with, and finding something that I'd really like like an ASR-33
might not happen any time soon. The model 28 looks like a serious machine. It feels
like something someone would have gotten cheap or free back in the day and found a way to
rig up for use with a computer. But maybe not. :)

There are two units. One is a "reperforator" so it should have a tape reader
and punch, but may not have a transmitter so it may only work in parrallel
Anyway, if I understood correctly, it was possible
(and possibly done in

No, the computer used to convert the ASCII to Baudot in special i/o
routines.
This one is out of my reach since the auction is pick
up
only. But I kind of like the look of the Model 28 and I understand
they're
pretty bulletproof once you have them working.

ago...

I have two model 28s: an RO and an ASR. The 28 and and earlier machines
are, of course, baudot machines which used five level tape instead of the
wider eight level tapes used in the 33 and later machines. They are both
floor consoles and completely self contained in one unit - this is in
contrast to the model 19 for instance that had, as far as I recall, a few
separate modules that sat on an accessory table.
The model 28 ASR in my possession is one immense and very heavy console unit
containing the printer, the keyboard, tape reader/writer, power supplies
etc. It is absolutely lovely and absolutely not the machine I want to use
to talk to a pdp8 or what have you. If you want a bullet proof teletype
console that weighs as much as you do, go find a model 37.
