IBM KB-9910 Keycaps PBT? Can it be Modded w/ Modern Switches?

[Alvin777]

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.

I guess you could cut out the stems in the rubber dome keycaps and replace them with 3d printed mx stems, I don't know how feasible it would be, if it's more trouble than it's worth and if it would even work with those caps but if you are never gonna use that membrane board and you were gonna throw it out, it can't really hurt to try.

I found some reddit threads that could help you get a start with this.

Good luck with doing this.
