[comp.sys.apple2] Zip chip blues

M Zip has beome quirky. It lives for about 30 seconds then goes random. 

In truth, I have upgraded the cache to 64k myself, so two things could be
wrong. There is a bug in the system that doesn't like 64k caches, or more
likely, one or mosre of the memory chips are bad. I am restoring the original
16k cache and will report back on the differences. One thing odd that I found
was that my Zip required 4 chips to be present in the cache regardless of how
the Dip switches were set, i.e. 8k or 32k caches. There may very well be a
design flaw. 

My version is GSX 1.02.
