    Better bite my tongue on that. What I said isn't right, you can
change cache sizes regardless of whether you have 8K or 32K cache
installed. A ZipGS with 64K can be toggled down to 32K, 16K or 8K,
or a 32K down to 16K or 8K.

    I just went and tried again, although _very_ unstable for some 
reason, I was able to toggle my 15/64 to other cache sizes. Sorry
about posting that error, in three different posts today no less, 
sigh... :/
