I found description of power-on-reset on original 84-key AT in IBM tech reference, it is  rather slower than I expected.
Could you try this new attached firmware and show me output of hid_listen when press a, s, d and f key? I need to know numbers of Ixxx and Rxxx in particular, like below.

USB configured.

--- Quote ---Alright, I built an entirely new Soarer's converter and the F XT is now working with that. I thought there may be something wrong with the other converter, but I think there was something flaky with the usb cable, grounding maybe, since once I removed the usb extender it would work. I still can't get the F AT or F XT to work with either version of your firmware though. At least the F XT doesn't spit out random keypresses though. So, I've tried 3 different usb cables and 2 different Pro Micros, one with and without the pullup resistors and a complete rewire, with the same results (once whatever was going on with the XT was resolved).

Do you test my firmware with the "new Soarer's converter", right?
Sorry but can you share output of hid_listen for F XT with this new firmware again?  Pressing a, s, d and f key would be helpful.

Maledicted:
I tried both previous firmwares with both the newly assembled Pro Micro, and the previous one that I had re-wired. The results were the same other than the F XT no longer spewed out random keypresses (most of the time). I noticed that with your latest firmware the F XT spewed out random keypresses on the rebuilt Pro Micro and did not on the one that I just newly built specific for this testing. That makes no sense to me since I wired them exactly the same way this time, with the extra XT wire soldered, and no resistors.

The XT did now give results with the new firmware, on the newly-assembled Pro Micro, when pressing the a,s,d, and f keys, although that didn't seem to translate into actual character signals that the computer understood when I tried to type out text. HID_listen detected nothing at all when I used the latest supplied firmware to press the a,s,d, and f keys on the F AT. I have attached the results of your requested test with the F XT:

 Ibm Model F XT output second alternative firmware, asdf pressed.txt (0.65 kB - downloaded 455 times.)

I don't mean to double post, but do you have everything you need, or is there anything else I can test for you while I have all of the boards in one place? I jump around between buildings at work, and use the DC-2014 especially at work, but also the F AT. I have been keeping them at home the last few days for testing this.

Maledicted,
Thank you for your service so far! I really appreciate.
I don't want to prevent you from using your keyobards anymore, feel free to place them back to where they should be when you need.

I'm debuging my code on keyboard protocol recoginition and signal handling and this will take some time. If this is not in time for your test, others in the community will help me in the end.

Thanks agian!

Maledicted:
Absolutely, anything I can do. Thank you for putting all of that effort into an open source project for the community at large.

Actually, since I posted that, I won another F AT and DC-2014 on Ebay, so I should have at least one of each available no matter what now. lol

Have others with the same boards helped elsewhere? I wouldn't be surprised if none had. I imagine a lot of people go, "Soarer's firmware works for me. I'm good." since all of these boards work fine already. I think it is pretty important to expand on the functionality of Soarer's work though myself, and being open source like that, TMK seems to have the potential to become the one catch-all solution in time.
