[GreenKeys] Connecting a Model 14?

Well, it's a relay. http://www.lintechcomponents.com/product/011680205/22800156111/31951 It's rated for 6 volts, and it's my guess that some clever person rigged it up to be keyed by a computer. Looks like the relay drives the power supply which in turn drives the selector magnets. If it were me, I would check to see if the unit still functioned, no stray voltages or unintentional grounds, or anything that would hurt the teletype or my computer. Then, by studying the schematics on John Nagle's site I would fashion a connector to use the serial port on a pc. http://www.aetherltd.com/connecting.html That should satisfy the hardware requirement. Then you need a program to drive the teletype. Heavy Metal or MMTTY? I have no experience with these and maybe someone else might jump in here. You have to be able to adjust the program to make the machine happy, flip or reverse the signal etc. Man, I love this stuff. Kevin

Oh, I'd love to play with that. Looks like a relay, transformer, some diodes and resistors. Rudimentary loop supply? Anyone want to bet that 5V will "key" the relay? What does the writing on the little green box in the picture say, Danny? Kevin

Hi everyone!I'm new to this list and just recently found out about it from Doug.  I've actually had a Model 15 laying around for many years with the intention of getting it to work. I recently came across a Model 14 that was in slightly better shape and figured it was a better starting point. With the help of John Nagle (http://www.aetherltd.com/refurbishing14.html) I was able to get everything in mechanically working condition (video: http://instagram.com/p/rhokFcFoiL/) My next step is connecting this thing up to my computer. In talking to John, he said that this circuitry and 1/8" plug is non-standard (picture: https://pbs.twimg.com/media/BuuQNJ_CEAAmSds.jpg) I'm curious if anyone knows what this is and if there is an easy way to plug this jack into *something* and get it working? Thank you all so much!Danny
