Oh no! Not another baud .vs.BPS.vs.data rate gentleman's argument!
But, What is a 300 Baud interface? Current loop maybe?

I was at a storage unit this evening, picking up yet
another couple of
free DEC machines. The guy unloading the machines also had a couple of
teletypes. One was a pretty standard Model 43 (all plastic case).
It had a 300 baud interface, not serial port. He said he knows it works
because he ran it to a computer at 300 baud that then converted the
signal to serial so that it could communicate "normally". He said the
300 baud interface makes it more of a pain, but more cool at the same
time. He is looking to unload it right away. The other teletype was
all metal, built into a small table, had an Army Corps label, a tape
read/writer?, a box of blank "new" paper tapes on spools about 5/8 inch
wide. Also a second auxiliary? teletype unit was built into a very
small adjacent table. This one had several "new" rolls of paper approx
12 inches wide. The secondary teletype had keys too, but I am thinking
the primary with the paper tape was used for input and the secondary
was used for output. The guy said it was used with the MARS system.
There was an interface box too, probably to connect to a ham radio,
but the radio was not present. The guy said he got it from a retired
Air Force General who had kept it as a souvenir. He said he has all the
original manuals that go with it at home. He said it is complete and
reportedly working. The only thing wrong was some of the plastic covers
on the individual keyboard keys had deteriorated and were loose.
However considering the year, 1938, it was in remarkably good shape.
The dry Colorado air is pretty easy on most equipment, and this was
yet another example of that.
He said cannot ship it because it is too heavy, but I know that places
like "The UPS Store" can pickup, package, and ship items like this.
There is a UPS Store nearby that might be able to do the job. (I had
a 100+ lb IBM machine shipped this way a few years ago for about $200).
Anyway, the guy is Matt. I am not going to post his email address, but
if you want to contact him, email me and I will forward your email to
him. I can also give you contact info for the nearby UPS Store. Matt
took some pictures with his smartphone for me, and once he emails those,
I will put them on a website.
