    Yes, it's possible to put a "split cache" on the ZipGS, but I don't
think it is worth the time and expense.  You also run the risk of
ruining your accelerator.  Stick with 64K of cache.  The performance
gained by another 64K isn't worth the risk.

    No.  The expansion connector isn't good for anything.

    If you're saying this because you see other computers with ratings
in the thousands, don't be disappointed.  The dhrystone is a measure of
compiler efficiency.  As we all know, ORCA/C isn't exactly at the top of
the heap in that department.  ;-)  Comparing dhrystones across platforms
and compilers is a worthless exercise.
