- Faster SIMMS will make absolutely *no* difference. Your computer will
- access the SIMMS at exactly the same speed, even though the SIMMS are
- capable of being accessed more rapidly.
-
- The PowerCache has 32K of 25ns static RAM cache on board, and it *will*
- access this RAM cache at full speed (i.e. no wait states). Since your
- most often-used memory is kept in this cache, it's nearly as good as if
- all of your RAM were accessed that fast.
-
- So you can take the money you would have spent on SIMMS and get a 40mhz
- PowerCache instead! :-)
