When I needed to create a PAL from a schematic, I
first made
a schematic of what the PAL was suppose to do, using the
same basic model of logic that the PAL provided. Once I was
done, I took the PAL map from the TI book and made red dots
on each of the connections I needed. I'd then go back
I thought I was the only one! Back when I first used a PAL, I
also photocopied the page from the databook, marked up
the connections I wanted, and then asked my coworkers
how to get that programmed into the device. It was pretty
annoying to learn I had to convert it to equations first. It
seemed like a pointless extra step when the software was
just going to turn around and turn the equations back into
the matrix wiring I had just marked up.
