I know they are almost a thing of the past but I wonder if there is any way to extract the code from a protected GAL IC (example: GAL16V8A) that has had its security bit set. I repair mostly old Commodore 8 bit computers. There are a lot of users of an after-market device called a RAMLink originally made by Creative Micro Designs (CMD is now out of business) back in the 1980's, and I was asked to repair a few of them. Turns out each one has four or five GALs and they all are copy protected which makes repair of those orphan devices impossible unless I can find a way to extract the code from the chips in a working unit. Any hackers out there?
