Hello, i have decided that i'll be recreating the schematics and dumping GALs for any bootleg that I lay my hands on. As it was common back then for bootleggers, some ICs are sanded off, most of them are 74 glue logic that I can figure out what they do by just throwing them on my EPROM programmer but others like op-amps and especially SRAMs are a different beast. Not to mention PALs and GALs which is pretty much impossible. How do you approach this subject?
