[Feature Request] AT Keyboard Converter

[Muirium]

Hi guys, longtime Soarer’s Converter user here, first time QMK. (All my QMK so far has been via Pandrew’s capsense port for IBM Model F and beamspring.)

I’d like to run QMK on my Teensy converted AT/PS2 keyboards. (Some have an internal Teensy, some hook up via their original cable to a Teensy in a box; in either case it’s always an AT protocol keyboard being converted to USB via a 32u4.) Ideally, I’d like to be able to select the basic, generic full-size AT layout in QMK Configurator, and define layers there to my heart’s content, then compile, download and flash the hex file to the Teensy. But I see no AT converters in QMK Configurator’s menu. Really? There’s ADB support but not the ubiquitous AT/PS2? Woah!

Here’s a thread I wrote about this on Deskthority. I’m not alone in desiring this:

I know my way around TMK Unimap and QMK Configurator a bit, as a user, but I don’t know how to define new targets. An AT converter would get a lot of use!
