I am thinking about getting a 486 -33 EISA machine from Tandon, but
they are advertising 64 bit memory.  I thought the chip had a 32 bit
addressing scheme with 48 bits possible with segments.  Does anybody
out there know whether this 64 bit memory is fact or fiction, and 
if fact, what's going on?  Also, are external caches for the memory
really worthwhile for DOS usage?  Thanks - jham@cs.umr.edu
