Re: XT Zenith Z-150 converter?

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 ...

Re: XT Zenith Z-150 converter?

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...

Re: XT Zenith Z-150 converter?

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. ...

Re: XT to PS/2 Converter for Model F

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.

Re: XT to PS/2 Converter for Model F

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...

Re: TMK IBM PC Keyboard Converter

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.

You can use the decorders of course, it would be easy to write code to use them if you can track traces of the pcb and find datasheet of the decorders.
