I have an 1186 which keeps completely freezing for no apparent reason.
(having been completely reliable for ages).  Everything stops,
including the mouse cursor.  Pressing the B-reset button blanks the
screen, and the machine then sits there, with the `scroll lock' led
on, and the screen completely black.  After leaving it powered off for
a while it comes back, for a while.

I've tried swapping the display card & the CPU card to no avail.  Next
I'll try the IOP -- is this a reasonable candidate?  If it is
reasonable, does anyone know which chip on that card is the eeprom?
It would be easier to swap them than reconfigure the new card.
