- That performance increase comes from the 9mhz, and if you increased the memory
- size of the cache then that will make it faster too. Faster cache ram does not
- affect the speed of the machine, it only allows you to run the CPU faster
- (which _will_ affect the speed of the machine).
-
- Jawaid is essentially correct; your cache ram is either:
- fast enough, and everything works
- almost fast enough, and the Zip acts flaky when it's warm
- not fast enough, and the Zip doesn't work at all
- FOR the clock frequency and CPU chip that is installed.
