Find a atleast somewhat doable calculation/algo/etc on your pga.
Hmm. OK. I was about to say it's not really for calculations or algorithms, just a way of chaining together logic gates....
But then I had an idea. I think I can show the usefulness of it.
There are ultimately more space-efficient (and also probably tick-efficient) ways to build a digital display, but a set of PGAs can be quickly copied and configured to build one. So as long as there's someone with worldedit available (as the FAQs seem to indicate there will be), I can build say a single hex display with my PGA. (e.g., given a signal strength of 0-15, display the corresponding hex digit for that signal strength on a simple screen made out of redstone lamps).
I'll need to build a (edit) 4-bit PGA for every lamp in the display. 3x5 is a good enough resolution to display letters and numbers, so I'll need 15 copies of the PGA I build, and then I'll wire them up to the display.
By flipping switches on each PGA, I can make the display do hex digits given a 4-bit binary input. By rearranging the switches (but not changing anything else) I can make the display output the letters A-P instead.
Sound reasonable?
(edits were because I was undecided on hex vs octal)
