	Has anybody got any info on the 030 in 68000 package?

Not directly.  BUT there's an interesting item in the June 1990 APDA Bulletin
(APDA = Apple Programmers' Developer Association) concerning assumptions
when the CPU (in a Mac) is "> 68000".

Previously, it appears programmers have been assuming that a math co-processor
accompanies any 68020 or 68030 based system.  They (Apple) have added a new
system call that specifically returns a value indicating whether such a
co-proc is installed or not (regardless of the CPU).  They didn't say WHY
they're doing this, but it seems to me that a system using the "new" 68030
in the 64-pin "68000" package would be a likely suspect, er... candidate.

If the new chip is as compatible to the 68000 as is the 68010, then this
presents some interesting possibilities for upgrading present 68000 and 68010
systems!
