Yes, this is a fairly comprehensive site, but,
wouldn't you know it, the first
thing I encountered, in looking for spec's, was that the item regarding the
Performa630CD clearly claims it uses a 68030 at 33 MHz, while the Apple doc's
and
http://www.info.apple.com/info.apple.com/applespec/applespec.taf?RID=180
both seem to agree that it's an MC68LC040 (an'040 variant, (probably degraded
... it is an APPLE product, after all ...) at 66 MHz AND a '486DX2/66. I
suppose the bus speed could be the rating base rather than some invisible
clock
doubler or whatever.
an 68LC040 is an 040, without the Math Coprocessor IIRC (LC = LowCost) you
can pull the LC040 (if it is socketed) and put a full 68040 in and get a
speed boost. the 486 chip is on a daughtercard that goes into the PDS
(Processor direct Slot IIRC)
