(...list of physical incompatibilities between '030 & 68000 deleted...)

Well, I don't know if there is any such thing as this rumored '030 in a
68000 package, since this news group is the only place I've seen it mentioned,
and EE Times is usually the first place I hear about interesting new products
like this.

However, it is certainly not impossible.  It would be done the same way
that plug-in-the-68000-socket '030 boards work right now.  ie, some glue
logic, drop the extra address lines, fini.  If it included a 68882 in the
same package everyone with a 68000 machine would probably go out and buy
one.  The required glue logic is inconsequential in comparison to the
internal logic of the 68030 chip.
