Apple could be timing the introduction of a 68020 based machine with
quanity shipments of 68020s. Summer might be a bit early, but end of
the year might be reasonable. 

The suggestion of using a 4Mhz 68020 is an interesting point. Motorola
claims that the slowest part will be 16.67Mhz maximum and can be clocked
as slow as 8Mhz. What is motorola going to do with all the chips that
will operate at 8Mhz but not up to the 16.67Mhz spec? They could be
used as the basis of a very nice pc.
