So IMHO as soon there is a real demand for it, somebody will create a replacement. Well, I agree more with Ruud, but the example is not well chosen because the PLA is easy (if we exclude timings problems, but if you use an EPROM, you're anyway adding different timings), CPLD versions of the PLA can be exact replacements even timing-wise. 6526 isn't so easy, it's a complex piece of statefull logic, but it's doable. There're probably still too many real parts to start worrying. FrankReceived on 2018-09-13 08:01:32
