This is one reason to stick with Socket 7 .. as the cache is now
directly wired to the CPU, it is not going to see any speed benefits
from a bus speed increase.  The Pentium II 100MHz bus will make little
difference to overall system performance, yet a Super 7 100MHz bus
will likely almost double performance.  As someone else mentioned,
Intel are making possibly the worst move in history and bringing out a
cacheless pII.  <laughter>

Or, if you have an antiquated pentium motherboard, you might be able
to remove the external cache .. has a poor effect, though your CPU
internal cache is still there.

the cache in the pII was wired in the way it was to reduce costs.
Slot 2 will have much more cache, and it will be running at full CPU
core speed, which will make for some fast little chips.  At one hell
of a price. :)
