Thanks for reply.
Is that all you got in hid_listen?
Debug output during the keyobard "works fine" and when "you turn on lock lights" would be helpful.

Can you post debug outputs long as possible here or somewhere like pastebin.com?

Thanks for your patience. And take care of your shoulder. Firmware you tried(TMK:f8ce50eb/LUFA) is old version from Feb 9 for some reason, not the latest one. Could you try download firmware file from here and test again? https://github.com/tmk/tmk_keyboard/tree/ibmpc_z150at_fix4/converter/ibmpc_usb...

Good to know that lock lights works now. These two issues are still left at this point. 1) Lock lights are not updated at startup. They won't correspond with lock status of computer after startup. 2) The keyboard doesn't response to 'Read keyboard ID' command(wF2) for some reason. I updated firmware...

Great!

Can you confirm that LED indicators works when pressing Lock keys?
Also 'F7' key works? (Monoprice converter fails at F7 for no reason.)

I still like to check debug output to know that it works as expected.
Posting debug log with pressing those keys would be appreciated.

I found a bug and updated firmware again.

Could you test this when you have time?

Thanks for your patience. That firmware version(b4a30776) seems to have regression on keyboard protocol recognition. (The keyboard is recognized as a XT keyboard instead of AT.) Power-on test result(rAA) from the keyboard is received but 'Read keyboard ID' command(wF2) fails and the keyboard doesn't...

Updated firmware with fix for Z-150.

https://github.com/tmk/tmk_keyboard/tre ... usb/binary

Feedback and hid_listen debug log is still required to improve its support.

Thanks

Lekrafter, Thanks for the test. In the first video: 'ERR:17'(and 'ERR:20') still occurs but it can be recovered with the latest firmware. The converter works with the keyboard probably. In second one(Repluging at USB connector case): No error found. The converter should work as well. The converter s...

Thanks for your patience, Lekrafter. I want to add support for Zenith Z-150 AT to my converter but it requires many trial-and-error process. Hmm, the log shows new errors 'ERR:11' and 'ERR:F0' this time, which seems to be caused by You can get 'ERR:11' again with another test? To reproduce consisten...

Yes, that is exactly what I asked.
It seems that the keyboard fails to receive command from converter.

Updated firmware for debug. Try this and show debug outputs when you have time.

Just did but it unfortunately doesn't seem to work, but at least now the beeper always works

Can you post debug outputs on hid_listen?
Check 'Debug' section on the first post of my thread.

You can try my firmware, it is compatibile to Soarer's converter.
https://geekhack.org/index.php?topic=103648.0

I have improved the firmware to add support for Z-150 AT, it should work except for CapsLock, NumLock and ScrollLock.

Are you sure that the keyboard worked correctly before you restored? And how do you connect it onto computer? directly to PS/2 port on motherboard, via PS/2-USB converter or ... I won't be surprised at all if the keyboard works weirdly regardless of your restoration. I have seen that people reported...

This problem is still there on Linux 5.4.0(Ubuntu 20.04.1). I didn't read HID spec thoroughly but I'd say Cherry controller is faulty rather than Linux HID stack. From natural interpretation of Appendix C of HID spec, keyboard should send 'valid' modifers in the first byte(modifer bitmap) of its rep...

Interesting is, that the beeper goes off for every key, except L- & R-Shift, Ctrl, and Alt. Any idea what the reason for that could be? 'Alt+Esc' is still available to toggle the beeper even under this situation? I don't have idea on this and the keyobard to test unfortunately. The converter can't ...

I think both issue is normal for the keyboard, not your or hardware fault. IBM XT keyboard doesn't has any LED indicator and XT keyboard protocol doesn't support it. Some clones have indicators and which are controlled just internally by keyboard itself but they are not controlled from host or conve...

Thanks for your mention on my project. Yes, it should work with XT Z-150, post in the thread(or here) if you have any problem. And now it requires testers with *Zenith AT Z-150* to add support for the weird keyboard. The converter can read scan codes from the keyboard but fails to control its LEDs. ...

Probably SW1? Share your result. https://deskthority.net/wiki/File:ARC_KB-5181_--_assorted_2.jpg https://deskthority.net/wiki/Chicony_KB-5181#Cherry_MX_blue_switches As you already found AT2XT converter is another option. http://www.vcfed.org/forum/showthread.php?15907-AT-to-XT-Keyboard-Converter&p=...

Sonic08,
What's model number of your "Model F XT"?
Its waveforms seems to be different from other IBM XT keyboards. The data line is pulled down to low when idle on IBM XT keyboards. Just curious.

You can use your "IBM Model M 1390120" your profile are refering to test the converter hardware and its cable connection at least?

AT waveform itself looks ok now. But the AT signal for 'K' is actually '6B'(Keypad 4), I think you got '4' or Left(depending on NumLock state) on computer press 'K' on the XT keyboard. This indicates the converter misread XT signal for 'K', to be exact, it fails to read data on the first clock falli...

Can you share model number of your "old XT mechanical keyboard"? That XT waveforms seem to be ok and clock is a bit faster than genuine IBM XT keyboard, but it won't be problem. I think the waveform of "At the output of the Converter" shows 'AA' from converter(emulating AT keyobard), 'ED' command fr...

frogmaster,
Thanks for your feedback!
It looks ok, the keyboard is recognized as expected.(AT protocol with Scan Code Set 2)

frogmaster, Interesting. I understand how the numpad part is configured now. Added the keys to keymap editor. It should make easier to remap hidden keys of IBM AT keyboard. Can you try this? You can load your existent firmware file at "Base Firmware File:" section and the editor should display your ...

Hey there, I just built a TMK ps2_usb converter out of this Pro Micro clone from ebay: Try new IBM PC Keyboard Converter(ibmpc_usb) ! This thread is for it :D Desoldered MIC5219 voltage regulator (the 5-legged IC), 2x 10uF (orange pieces), diode D2 (middle and right next to USB socket SMD pins). Br...

frogmaster, Oh, AT keyboard. I assumed your keyboard is XT becasue you refered process_cs1. I didn't realize missing keys on AT editor but I'll add them. The misssing keys are 39 and 68 in scan code? Is there any other? https://www.seasip.info/VintagePC/ibm_6450225.html And can you post pic of your ...

What is your keyboard model? You refered only 'model f'.

Which key are you refering? Posting pic is helpful.
"EXTRA_INSERT (0xb6) is missing from numpad (should be left of NUMPAD 0)."

Well for start, EXTRA_INSERT (0xb6) is missing from numpad (should be left of NUMPAD 0). What is the button i should select on the editor? First, flash firmware downloaded from Keymap Editor(without edit mapping). Then press the key on your keyboard to know what it registers on computer, you will n...

I think if you do some trial and error on Keymap Editor you will know how to use it somehow.
What's your problem actually?

That remap looks to me really straight, though, I don't know much about how Soarer's remap setting works. You may need to explain me what you want.

I also tried the dial on my 98203C with wiring cheap usual mechanical encoder tentatively (it failed to read optical encoder I got for the keyboard, for some reason), and found that it sends Y-axis data when rotate the dial with pressing Shift key. I can move mouse cursor with the dial now. I ported...
