[comp.sys.mac.hardware] Sick Mac 512K

Hi, I wonder if anyone can help me with a couple of problems:

I have a Mac 512K, un-upgraded.  Recently when typing, the screen has
filled up with the right bracket character ']'.  If I click on the
maouse to select the text, it sometimes stops the characters from
appearing, but only for a moment.  The ']' key is not stuck or
anything like that, and it is only this character that appears,
independently of what character I last typed.  If I change the key
repat to 0 on the control panell, the characters slow down
significantly but do not stop appearing.  If try to type when the
characters appear, characters other than the ones I type sometimes
appear as well, although the system usually reverts back to repeating
the ']' again.  If I unplug the keyboard while the characters are
displaying, they stop.  The problem appears after my Mac has been on
for a while (i.e. not immedialty when I start up), so I suspect it may
be heat related.  Any ideas?

The second problem is that my disk drives no longer eject their disks
without help from a paper clip. Can this be fixed?

I would appreciate any replies by e-mail, since I don't ususally read
these newsgroups.

Thanks in advance,
