Ah, I misunderstood; I thought you meant just relabel the keys. Mind you, rewiring
the matrix would make the keyboard incompatible with the C64 (although it'd be a
relaxing project for a Saturday afternoon...)
I didn't mean that it _had_ to be defunct, just that if you only had a non-repairable C64
this'd be a good way to have its equivalent; if your PC had video out as many of them
do these days, you could even hook it up to a Commodore monitor for the real look&feel.
But if all you need is input from a few buttons or switches like for a dedicated MP3
player for example, using the guts from a keyboard is a quick & easy way to go
(as ethan described); have done that too for a few projects. Interesting to see how
they've shrunk over the years, from 2 or 3 LSI and a half-dozen TTL glue chips to
a tiny blob of epoxy...
