Any chip that features at least 16 inputs and 8 outputs (or e.g. 24 programmable I/O pins) will do the job. But I think that the cost will be higher than that of a C64 PLA (or a broken C64 that has a working PLA). The replacement does make sense for rarer machines, such as the PET product line or the 264 series. Marko Message was sent through the cbm-hackers mailing list
