I got a bit of somewhat tongue-in-cheek flack recently over using a
PIC for my four-phase clock generator, where dedicated logic would do.

I was only planning to build one or two instances of the circuit, so
it wasn't particularly cost-sensitive, but still, it seemed like using
a PIC was both the simplest and least expensive solution.
A TI SN74LS362/TIM9904 would have done the job, but I don't have any
on hand, and they're now relatively expensive and hard to get. (Anyone
have one or two pieces spare?)
