On the other hand, the C64 can do 36 dhrystones/sec (according to the
machine rankings included with the dhrystone benchmark source), while
a cached 386-33 does a best-case 13500 dhrystones/sec (according to my
own measurements: dhrystone 2.0 compiled with MS C 5.1, generating
286-specific instructions, using the register option).  Thus a 386-33
is 375 times as fast as a C64.

I think this means that a cached 386-33 can emulate the video features
of a C64 at full speed.  At least.  But why would you want to?
