- And I'm saying that unless there is something you aren't telling me, what you
- are saying shouldn't be possible. Simply plugging in ram chips with a faster
- speed rating should not affect ANYTHING except the reliability of the Zip.

- The only way I can believe your statement as you worded it is if the Zip
- has some special circuitry for detecting when cache ram is too slow and
- automatically slowing down to accomodate it. I know of NO cache system that
- can do this, but I also do not know for a fact that the Zip doesn't attempt
- to do it, so I have to admit it's a possibility. But I am very skeptical.
