I mean for building cards and programming. The chips usually used are a bit small for my liking, and above 40 pins means too complex to me. With all those pins, why did they multiplex the data and address?
I work all the time with 1000 pin chips and it doesn't bother me at all... just keep the specs of the bus you work with handy and everything will be ok. (when in doubt, look at the specs)
And they multiplexed data and adress to save pins. (especially in chips) : at the time that bus was developped, you couldn't have more than 100 pins on a chip, so you had to make some sacrifices and multiplex a few things.
PS : and the ISA bu will be obsolete only when no one uses it anymore !!! long live ISA !!! (lol)
