Recently my C-128 has started acting very oddly, it throws random characters as
if I were typing them but I'm not. Sometimes it acts like I press keys even
when my fingers aren't on the keyboard, and sometimes it will add random keys
among the actual 
keys I am typing.

OK, this is old hardware, and things happen... but it was flawless until now.
What would be a fix for this -- does this sound like something "recapping"
would address? I am pretty clueless when it comes to hardware issues.

Is there a diagnostic image (in D64 or D71 format for an SD2IEC) out there that
might help?

Thanks.
