	MC68000P8 is Motorola's part number for an 8 MHz 68k in a plastic
package, not to be confused with a MC68008P8 which is a 68000 with an
8-bit external bus.

	I, too, would like to see more technical info on the ST.  Can
someone out there oblige?

Sorry, I can only help with the 68000P8.  That means that the 68000 processor
is the 8 Mhz version.

It is the same one that is in the Apple Macintosh.

The P8 means plastic package and fully tested for 8 Megahertz operation.

Hey, I can help! I just received my software development package from Atari,
and it has just tons of documentation. I'll just look through this stuff for
some neato hardware specs (like the ones that came with the 800 technical
manuals.) Wait right there while I look for the specs.

I'll be just a few minutes.

I know there here someplace.

Uh, maybe I put them over there.

Jeez, I can't seem to find them.

Oh well, :-)
