	Two questions:
	
	I've run seceral benchmark programs which tell me that the speed of
the CHIP ram in my A3000/25/50 is running at only 85% or so of what it
should be.  I popped open the case to take a look at the chips in there,
and found that the ones soldered on were 100ns chips!  (The ones I moved
over from the fast RAM section were 80ns, though).  Seems to me that
100ns CHIP RAM on a 3000 would cause a bit of a bottleneck... why does my
machine have these slower chips (apparently some 3000's have 80ns CHIP RAM,
and the benchmarks I've run are based on that...)

	Also, I've heard claims of measuring 1.2 mbytes/sec with DiskSpeed.
With what settings was this achieved?  On my 2M chip 2M fast system I've yet to
get anything that high.
