Hey all, I have an IBM 3479JA4 (IBM 5576) keyboard that I got recently. I got it all cleaned up and I'm trying to use the thing, but I'm having a heck of time figuring out what is going on.

I can plug it into my computer's PS/2 input, and every normal key behaves as it should. Every non-standard key makes the computer beep (Windows 10). Because every key behaves normally or at least provokes some sort of response, I know every switch physically works.

I can plug it into a monoprice PS/2 usb converter, and it's pretty much the same thing, any standard key is fine, any non standard key is just ignored.

Things get screwy when I plug it into my Orihalcon Soarer's converter, though. The converter works perfectly fine with my Focus 2001, so the converter as far as I can tell is working properly.

Here's the HID Listen output for plugging it in, then pressing "a" 5 times:

Code: Select all

Waiting for device:......
Listening:
wEE R100wF2 R100

remaining: 0000


Keyboard ID: 0000
Code Set: 2 (extended)
Mode: AT/PS2

It kind of works, it'll send the make code, and then after that the next press sent a break code, and then after that it sends some codes but not anything that translates into a keypress. Some presses half work, but mostly it just outputs gibberish. I've looked through the docs but I can't seem to find any info about the codes that it's sending.

Can anyone point me in the right direction for troubleshooting this keyboard with soarer's converter?

I don't know about Soarer's Converter for this but the TMK IBM PC USB converter works flawlessly with the 5576.

Good to know about the TMK one. It seems to work with my home-made PS/2 converter as well (That I use for a different board), so I'm not sure why it's having an issue with the Soarer's converter. If it comes down to it I'll explore other options, but since I already have this Soarer's converter I'd like to use it if possible.

[joke] I'm sorry. It won't work in any configuration. [/joke] [serious] So, you must sell this keyboard to me as soon as possible. [/serious]
