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.
