I couldn't see remoting my self more from the design. The JEDIC file is specified, the fuses are numbered why do we need the added steps. I was told the same thing, that there was no way other than to use a PAL compiler. If you really want to confuse things, try using a PALASM or such to move from positive logic to negative logic. Another use for the tristate is to make an OC output. Dwight

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. BLS
