Robert, "Fatal Error 0911" (on the new ROM) is the same as "Fatal Error 0400"
on the old ROM.  It means that synchronization between the IIgs and the
Keyboard Microcontroller (which is surface-mounted on the motherboard) has
been lost.  The problem occured for me with the old ROM and still occurs with
the new one.  I know of no solution to the problem.  It seems to be related
to the IIgs's temperature, but I haven't done any scientific experiments on it,
and I can *not* reproduce the problem on purpose.  (It just happens when it
is least convenient, but never when the machine is cold.)

I have had the problem on power-up (with the machine hot), on any form of
RESET, and on Apple-Ctrl-ESC.  [Apple-Ctrl-ESC is the most annoying time,
becuase the chance of being forced to reboot means you have to save your work
before using any CDAs--it kind of defeats the purpose.  By the way, why do
so many publications get Apple-Ctrl-ESC screwed up?  I have seen it in print
lately as Apple-Shift-ESC and even Apple-Ctrl-"Restart"!]

I have not heard an official Apple statement on the problem, but I would like
to.  If you want to write them about it, give them some hard evidence that
there is something wrong:  do a self-test (by holding down Apple and Option
(note that Option is Closed Apple for //e upgraders) while pressing and
releasing Ctrl-Reset.  You will get "System Bad 09....." (can't remember the
last part of the number).  The self-test on the old ROMs will actually crash
if it detects the keyboard micro problem.  The self test will report "System
Bad" if you do it after you get the fatal error; most of the time your system
will self-test just fine.
