From the project
Replacement keyboard using Cherry MX switches, for if your Osborne 1 keyboard had a bad membrane like mine.
I think there are some Osborne 1 keyboards that are a different layout, which this may not work with.
If your Osborne 1 is like mine, I need an ISO '3' number-row key with £ sign instead of #. I think this comes down to the ROM in your system.
This is a slightly advanced project to mount to the original enclosure. You must: - Shorten the original 8-32 hex spacers to about half, or buy the replacements in the BoM. - Shorten the original 8-32 bolts to about 4.5mm thread length, or buy replacements. - Figure out how to stop the PCB flexing in the middle. Two holes on the PCB are provided to…
