From article <1532@aucs.UUCP:, by 870646c@aucs.UUCP ('Barry Comer'):
: P.S. Had one of those 16Mhz 68000 boards from CMI, the best increase was during 
: the float benchmark where it showed a 47 percent increase, but at the same time
: it showed no increase during the sieve benchmark. I had to return it because
: it would not work in "TURBO" mode after I added the Kickstart 1.3 rom to my
: 2000 for autobooting from the hard disk. It would boot fine, but when I ran
: the software that switches the speed the machine crashed, so I guess that I 
: will have to "PUT UP WITH" a 68020 board(life is a bitch sometimes).

	Hmm, sounds like you didn't call and ask... We've noticed a fair amount
of the new 1.3 ROMs that can't handle 14MHz accesses. The solution is to remove
the 'Fast ROM' jumper (J2) from your Processor Accelerator. You get a little
less speedup on ROM routines, but still benefit from the faster processor. Not
as much of a speed up as a 68020, but still a lot less expensive!
