TM-710 Keyboard Update
I've been working on a smaller version of the adapter that would be line powered. I split up the system so that I can read the mic, keyboard and output to the radio as I noticed the mic was used on other radios as well. A prototype has been built and tested and with a non-lighted PS2 keyboard current draw is right at 97 ma. On the prototype I included two RJ45 jacks but I'm likely to make thru hole headers in the next version to allow short traces, smaller board, and the ability to put in a project box with just grommets for the RJ45 leads. I figure everyone can either buy a premade RJ45 or make the cable they need and a coupler or punchdown jack to the mic is easy enuf to come along. Anyways if you have any input now is the time to say something. I will be doing a small run of these boards within the next week or so.
