My Byte's are in the middle of the input stack. Could someone please
post the DATA that shows a 68040 @ 25Mhz to be faster than a SPARC @ 25Mhz?
(yes, I've seen the Motorola ads that show the 68040 to be 20 mips versus
a SPARC's 18.... :-)
On the good side of reality, plaudits to UNIX/World, which has started
publishing SPEC numbers (full charts) in some of its workstation comparisons.
