Osborne O1 Keyboard issues

Working away on the recently acquired Osborne 1. Seems there's something
wrong with the KB - and if I didn't know better, I'd say it's a case of
The KB connector is 24 pins, double row header like a short floppy or IDE
On the KB side, there are two "shorted" groups of pins. Group one is 2X
shortred pins, group two is 5X shorted pins.
Thing is, this KB is not really built to be serviced, best as I can tell.
The switch matrix is made of two layered flexible circuits, and the key
assys are 'riveted' in place, by melting over the plastic pins. So I see no
way to disassemble it and give it a clean.. and then, even so.
With such limited access, I don't see many avenues other than flushing with
solvent(s) and hoping for the best.
What's to be done? Is this one.. done already?
