I've been offered a TeleType Model 15 or 19 with Western Union markings.
Does anyone know if this can be used as a printing terminal with a
computer? I'm guessing it'd be current-loop and not RS232.

James - this can definitely be used with any machine having a serial
port and that can be coerced (somehow) into talking in 45.45 baud ITA2
5-level code.... you'll need to key the unit with a current of 60Ma at
around 115VDC. Much modern hardware exists for this purpose.
Go here: www.rtty.com for a ton of info and links to several programs
and hardware interfaces for this, and I'd suggest subscribing to the
Greenkeys maillist - which you can also do from the RTTY pages. Also, you
can go to www.shoutcast.com and search on the word 'teletype' for an
audio-coded (AFSK) stream of news and info via Baudot code... you'll need
any of the popular RTTY decoding programs (I use TrueTTY or MTTY) and of
course Winamp or something to get the audio decoded. Of course the output
of these will be to your screen, or a file which can be printed later.
The model 15 (and it's UK Creed analogs) were the first computer printing
I/O devices, plus they're getting rather rare nowadays.
Many of us here on Classiccmp are also ClatterPrinter lovers, as well as
hams who are into radio retro-tech.
I personally have a Model 19, a 15, a 26, four 28s and a 35. Not all
running at once though - can you imagine the Noise that would make???
I also have the complete docset for the Mod 15/19 and associated
peripherals, desks, cabinets, etc, of you need.
For sure rescue the old girl - even if it turns out it's not your cuppa
- there are plenty of folks waiting to adopt these machines.
Cheers

A single 'k' at the end of a CW transmission means "invite to

hit the 'SEND' button.
And I hate when that happens... ;}

That's a wonderful collectible, most definitely in the 'antique' class. I
would take it for that if nothing else, as those particular machines are quite rare these
days.
Computer-wise? You would have to teach your computer to speak five-bit Baudot code. The
15 and 19 (a version of the 15 with a paper tape reader/punch) used it.
Yes, it is current-loop, but it's 60mA as opposed to 20, and the loop voltage is 130+
DC.
If you're going to get it, get it for the 'museum' value, not as an actual
use-it-everyday device (unless you want to stick it on amateur radio RTTY).
Happy hunting.
