[comp.sys.mac] Keyboard problems on a Plus

THIS IS A REPOSTING.  AFTER SUBMITTING THE ORIGINAL, MY MAIL
NETWORK WENT DOWN FOR A WHILE, SO THAT ANY RESPONSES WOULD
HAVE BOUNCED.  SORRY FOR THE INCONVENIENCE.

My keyboard is not processing keystrokes properly.  This is most
evident in the Key Caps desk accessory.  When I am using Key Caps,
the screen continually toggles between the images of an extended
Mac Plus keyboard and an (original) unextended keyboard.  Because
this is happening, keystrokes are accepted only sporadically.

I have empirically found that if I have a disk in the internal floppy
drive, or simply hook up an external floppy drive, the problem is lessened
although not completely eradicated.

My system configuration is as follows: an original 128k Mac, which was
one of the first to be upgraded to a Plus (it has the very first Plus
ROMS); 400k external drive; unextended keyboard; 40M CMS MacStack; and
standard 1M RAM.

Any suggestions as to where the problem may lie (and how to fix it
without an Apple dealer) would be appreciated.  Please respond via
EMAIL, and I will post a summary if there is enough interest.
