mhm... I don't know about actual processor's HCF cases (but I known 
about the Commodore PET 4xxx's "killer poke", that is, see below)

sure wasn't another "killer poke" case ? (that is, a peculiar setting of 
a peripheral control register whose put the controller chip(s) in an 
abnormal too-fast-switching condition until, well, frying it) ?

This also makes sense in the context of (glass) terminal hardware 
debugging, after all (the PET's killer poke involves the CRT controller 
chip)
