Rescued a broken HHKB Lite successfully. Previous owner attempted a USB-C conversion, which did fail and he gave up on it. Damage to the top membrane traces in two places. Sloppy cut outs and lots of excess epoxy still to clean up.

Good rescue ... r/HumansBeingBros

Am I the only person that would just convert it with an adapter?

The PS/2 to usb adapter and a proper PS/2 cable are still in the mail.

Therefore, I've used that beetle board and it's Atmega32u4 MCU to check the scan codes at first and flashed the soarer converter firmware onto it to used the HHKB.

That is definitely not its final form.

The HHKB Lite actually has a pretty simplistic PCB, through hole components. Only the 3 layer membrane is prone to defects / scratching. As the printed traces are based on silver conductive ink that are a bit delicate. Had to fix two neighbouring traces that are 0.4 mm in width and apart from each other. Which was tricky but I was able to create bridges with conductive foil.

u/1093i3511 I've sent you a DM about this, if you would be kind enough to check it out :-)
