The ones I dumped are partially incorrect. At least, the GAL programmed with these equations did not work properly (the MultiMAX cartridge displayed RAM test error). I think the PLA did not read correctly in my EPROM burner - sometimes reading the chip several times would yield different results, etc. Maybe the PLA is too slow for the burner which expects a faster EPROM. Later I will dig my old Willem burner which allows setting arbitrarily fast (or slow) chip reading, and will try to read it again. Regards, Michau.
