Hmm, then again, NMOS circuitry doesn't have the same sort of power dissipation curves as CMOS. (CMOS draws more and more at higher speeds, NMOS consumes a lot at low speeds, but not much more at high speeds -of course, it's so much higher consumption by default, that you'd need a really, really fast CMOS chips to actually consume more . . . let alone if there's a big disparity in interconnect size -ie CMOS chips would also tend to use newer, smaller processes -I believe most of the 68000s being produced by the early 90s were 1 micron)
There's just not enough silicon/logic used to have overheating problems, I guess.
It also seems like a surprisingly high percentage of old CPUs can be substantially overclocked without crashing (the systems themselves are generally the limiting factor, so with that aside, it seems like a lot of older CPUs are stable well above their actual ratings).
It makes me wonder why more manufacturers weren't overclocking CPUs as routine. (with any really unstable chips not meeting benchmark standards being used in down-rated systems -or just accepted the occasional return of a bad machine if the failure margins were small enough)
Heh, you mean people trying to pull 5V from the 7805, but accidentally pulling the unregulated 9/10/etc external power instead?but if I feed 12V in it then we'll get some damage, and I'm quite sure 12V is the number 1 killer... people like following guides that use 7805 directly as source for power, and people also like to strip wires very long, or do mistakes, and then wonder why nothing works afterwards
Oh, reversed polarity and kill things too . . . even going through a voltage regulator, it can fry things on the system before the regulator blows. (that happened to some of the main chips on a VCS I have -literally blew a chunk off the package of one of them)
Heh, and then there's crazy stuff like this where the CPUs can self-destruct:
Yeah, just a minor engineering flaw, right?
Oh, and then there's proper soldering coppers used with a small soldering furnace (we used those in metal shop back in middle school).
High wattage soldering irons are also good for wood burning. (for inscribing, stenciling, and such)
I really need a finer tip for our soldering iron, we probably have some somewhere, but I'm not sure where. (as it is, it's not too bad, but not great for really fine stuff)
One of those cold heat things might be good for really fine work too. (also less worry about burning the board or case)
