[GreenKeys] Text to Baudot

Fri May 12 13:52:57 EDT 2017

I have nine C64s here in my basement, most of them working in some fashion.
One of the many projects I have on my plate is to frankenstein them all to
a few 100% working, physically complete C64s. While I've also been
interested in building a text to Baudot interface (and vice versa-- I'm
also working on joining the i-Telex network), mine has been focused on
interfacing with modern technology for the purpose of wider capabilities.
That being said, I'd be extremely interested to get more information on
your software and wiring a C64 up to a current loop. I have the military
labeled M15 and M19; getting them talking to one of my Commodores would
perhaps be among the chief accomplishments in my life.
