I used to program Vax serial #1 at CMU in the mid 1970s. I moved to Portland upon graduation in the late 1979s and at Tektronix I also programmed (and may have in kit/o/crap in the basement) the pre-68k that was not yet numbers (I might even have notes like what worked and what did not. I remember their were early sequences that would fry the processor and I was always scared I was going execute them accidentally ) That processor was delivered 3-4 years post Vax [we used it to build Magnolia - Tek was one of the 10 test sites that had them and like Moto used an 11:70 state as the development cause vaxen cost tool much. 😉
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)
