Subject: Looking for: Parts keyboard for chicklet PET (or just a "-" keycap)
Made good progress with the PET; after fixing the
video I got the reset
circuit humming again (a bad ceramic cap on the 555 trigger circuit) and
it fired right up after that, much to my surprise. And only 4 of the 18
6550 RAMs are bad :). Replaced a few terrible sockets and it's running
reliably, albeit with only 6K of RAM.
The keyboard on this thing has suffered some abuse; the "-" keycap on the
numeric keypad has been broken off. I figure it's a long shot, but does
anyone happen to have a spare "parts" quality keyboard they'd be willing
to sacrifice a "-" key from?
Thanks,
Josh
