  Wait a minute... The VXL-30 memory autoconfigures as the first 2 MBs
of fast memory, then the rest of the 6 MBs autofigures for 8 MBs of fast.
The memory is contiguous, I don't have the VXL-30 memory mapped high(although
if I could get the 1 MB x 4 chips, I would have 8 MB 32 bit mapped high and
8 MB 16 bit fast). 
 
  I have not grabbed any files yet, just the FAQs.  I figured to do a little
research first.  Thanks for the info.  BTW... the 68030 is really a 50 MHZ
68030 running at 40 mhz(theory is if I wanted to run it at 50 MHz, I lost
burst and needed a new DMAC, someday I try to "push" it but for now 40 Mhz).
