Very cool for 1974. Mom cooked a meatloaf in it in a bundt pan. Came
out indistinguishable from a lawn tractor tire.

There was a later PPS-4/1 single-chip version. I
don't know how popular
this
stuff was but I wonder if there aren't more PPS-4 systems buried in
equipment
and appliances from the period than is commonly known. (I have wondered,
for
example, what the 70's-era Amana Radarange microwave ovens used for
control.)
Umm...mechanical timers.
