More on RocketChipII

["Frank Townsend" <ftownsen@iamdigex.net>]

I installed the chip into a memory-expansion-ready (? PEEK(64447)=3) IIc and
was NOT awestruck with the increase in speed.

I also ran Michael J. Mahon's Sound Editor (highly recommended!) and noted
normal sounding playback of a digital clip, which I thought strange since
Sound Editor requires that speaker accesses be slowed down in accelerated
Apples.

Does the RocketChip need to be switched-on somehow, or are there performance
bottle-necks somewhere else that prevent me from seeing much obvious speed
increase?  Other things I might be doing wrong?
