Hello extreme keyboards friends. Are the keycaps on the IBM KB-9910 made of PBT and could this keyboard be somehow modded to mechanical switches using modern switches getting rid of it’s dome and membrane system?
Thank you. God bless you.
Not 100%, but I am 99% sure the caps are lasered ABS from the looks of them. It could be modded to mechanical switches, but would be a huge undertaking. This thread is about someone who did something similar to a Dell Quietkey bigfoot so you can get some ideals. He used a PCB & just cut away all the areas where the switches go for a plateless build. Not sure you’d find a PCB that’ll fit that case though. In that case you’d be looking at using the existing chassis for a plate. Which would require you to hand cut each hole bigger to fit an MX switch & holes for plate mounted stabilizers. Then you’d have to handwire the whole mess together. If you can find a PCB that’ll fit in the case I’d say it’s worth a shot, but as far as the handwiring way goes I wouldn’t waste my time on that TBH.
