    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

John
