Also how cool would it be to have a little web interface so that you can see codes being sent/received, or even being able to change key codes with it too. I wish I had more programming skills!

I'm hoping to reprogram my Soarer's Converter to work fully with it, I've kind of got to the point where I'm hoping I can just configure the controller and it's not going to be impossible with the firmware. 🤔

Gammitin (Ben) 💾 (gammitin@mastodon.social)'s status on Wednesday, 14-Aug-2024 04:54:45 JST Gammitin (Ben) 💾 I have a mechanical keyboard from a lunchbox laptop (1990), it has 5 connectors (2 are ground). I've figured out VCC and I can get the lights flash on, like it's switched on properly. For the life of me I cannot get the clock and data to work via a PS/2 to USB converter. 🤔

Gammitin (Ben) 💾 (gammitin@mastodon.social)'s status on Wednesday, 14-Aug-2024 04:54:44 JST Gammitin (Ben) 💾 I have looked at the keyboard's microcontroller datasheet and identified clock input and the clock output pins, then the identified the correct clock output to the PC.

Gammitin (Ben) 💾 (gammitin@mastodon.social)'s status on Wednesday, 14-Aug-2024 04:54:44 JST Gammitin (Ben) 💾 I think it may be 'PC/AT', I've removed all caps and they're all fine, also the microcontroller is working too. So I'm going to see what I can do for PC/AT to USB conversion. This is crucial for my Cyberdeck build, if I can reuse the keyboard, then it's off the cards for now.

Gammitin (Ben) 💾 (gammitin@mastodon.social)'s status on Wednesday, 14-Aug-2024 04:54:43 JST Gammitin (Ben) 💾 D0 is Clock output to the computer.
D1 is Clock input from the resonator.
The keyboard is not switching on as it's not being told to buy the computer.
So it's confirmed that this is most likely to be an AT based keyboard (I don't think it's XT as it was a 386 laptop). -

Gammitin (Ben) 💾 (gammitin@mastodon.social)'s status on Wednesday, 14-Aug-2024 04:54:43 JST Gammitin (Ben) 💾 The microcontroller is fed by a ceramic 6Mhz resonator, which I have verified is doing its job correctly:

Gammitin (Ben) 💾 (gammitin@mastodon.social)'s status on Wednesday, 14-Aug-2024 04:54:42 JST Gammitin (Ben) 💾 I've flashed Soarer's Converter software onto my ATmega32U4, confirmed it's working, connected up my vintage lunchbox PC keyboard and nothing, it still won't work. 😞🤔

Gammitin (Ben) 💾 (gammitin@mastodon.social)'s status on Wednesday, 14-Aug-2024 04:54:42 JST Gammitin (Ben) 💾 To progress it looks like I'm going to have to make a USB converter with Manak1n's software, using at ATmega32U4. Hopefully this does the trick and the laptop wasn't sending some unknown commands, that I have no way of knowing:

Gammitin (Ben) 💾 (gammitin@mastodon.social)'s status on Wednesday, 14-Aug-2024 04:54:42 JST Gammitin (Ben) 💾 A standard active PS/2 to USB is not going to cut it, it's most likely waiting for a command from the computer to switch on. Here's the AT hex codes sent from PC to keyboard:
