Mark,
There's a command written by Greg Tibbs and included with the PP&S 040
cards that will copy Kickstart to 32-bit RAM on the A4000. Guess what,
though? The speedup is almost NIL! Between the fact that the ROMs are
32-bit and the fact that most ROM routines get cached by the 040, what
copying Kickstart to RAM does primarily is waste 512K of RAM… The
command is called FastROM040, and I've seen it on BIX and GEnie, if you
want to try it. Just put it before SetPatch.
Isn't there a little pot next to the clock for adjusting its speed? There
was on my Rejuvenator, and I thought the 2000 had one as well…
