All 16MHz Macs will run as fast with 120ns chips as with 70ns chips.  The 
wait states are hardwired, regardless of memory speed.

Apple is not dumping.  80ns chips are really a waste in anything less than
a IIci, unless you get an accelerator card.

Apple deserves flaming for somethings, but this isn't one of them.
