Responding to: ???'s previous message
how can you adress hundreds of I/O with only 4 ports and without a bus

The discussion is NOT whether you need a bus, it is about whether you should discard your 82.. chips.

In my previous post I mentioned two bus based designs, one using CPLD, the other using IIC.
