I still am in awe at the speed of the average personal computer.
When programming the analysis software for the PAL "cloning" project,
I was concerned about running nested loops inside of an outer loop
that iterated 65K times (PAL16L8 chips for example, have some tricky
aspects, such as tristate outputs and feedback lines), remembering
how long a simple 65K decrement-and-jump sequence took on a 4MHz Z80
(about a second, if memory serves).
Of course, it didn't matter. The analysis finishes near-
instantaneously. Running a truth table with 16K entries through
Espresso also completes in almost no time at all.
I'm clearly of the "old' mindset.
