How exactly do PAL chips get programmed?

As some of you might recall I was looking for drivers for my Tokamac II FX PDS card on my mac IIfx. Well I found the drivers from the original company founder. I read in Macworld (and had it confirmed from the company contact) that you need a PAL chip on the IIfx reprogrammed (or replaced?) because Apple screwed up BUS mastering on the IIfx and nobody caught on at the time because those types of cards were rare. Well I have found another person who has the same card AND the PAL chip needed on his unit but is having other problems getting his setup to work. What I want to know is are PAL chips somewhat like eprons in getting programmed or is there some other process involved? Does anybody know of a way to get a pre programmed chip dumped so it can be duplicated or do you need the original chip (or code) to do this? If I can be duplicated does anybody here have equipment to do it? I just want to get this card running being thats its rare and a cool upgrade for a cool machine. Does anybody here have any experience with a IIfx running a Tokamac II FX upgrade processor?
