i reported the crash a few days ago. i now have the maintenance
manual, and it confirms that the power supply is fine: both test
criteria are satisfied: the led on front of the case  lights up, and
the keyboard emits its desired aqueak.

however, there is no output either to the monitor or to serial port A
when i power on while holding down stop-d. the heyboard LEDs go on and
off twice, and then i am left with the cap locks led on permanently,
and no other signs of life. 

this leads me to think that the boot PROM is fried. would a fried boot
prom cause a crash in mid-operation? a fried boot PROM would fail in a
manner similar to  what i have described.
