There should be absolutely no problem with the INBOARD, since the INBOARD 
the ideal arrangement: The ending address for caching is set by switches
on the card. Typically, one sets them for the end of physical memory,
while dual ported and memory mapped registers are addressed above this.
I have checked this point out with INTEL technical support: the INBOARD
is completely compatible with cards like the W.G.E. because the cache
does not function above the end address.

Please post your results Terry - I'd realy like to know if you get
X up on XENIX. Are they offering V11 yet?
