I am aware that it's not always possible due to security fuse, but I would like to at least try to read the fusemap from a certain PAL16R6 chip. I would like to do it using MCU like Arduino, not a dedicated expensive programmer. Problem is, that I can't find any info regarding programming/verifying algorithm for PAL's.
The TI datasheet for PAL16R6 contains only this short information: "Complete programming specifications, algorithms, and the latest information on hardware, software, and firmware are available upon request", and that's all. So, is there any document/open source software/anything which I could examine to find some information regarding procedure of programming and reading back PAL fusemaps?
