Well, the ps7500fe is highly integrated, but going through cirrus' pdf
on it i can't find any mention of a hardware watchdog.
There's also a small ASIC (well, Lattice calls it something else but it
sure sounds like an ASIC to me), as well as a significant number of
small ICs on the board. I'm not sure what the minimum hardware
investment in a watchdog is, so, I'm not sure what to look for. I mean,
if I started cataloging ICs and found one that phillips identifies as a
watchdog, sure, but, that sounds so unlikely it's silly.
I suppose we could try something drastic like severing the reset pin on
the cpu. Real hacking starts with an x-acto knife, yaknow ;-)
