Oh, thank <insert-deity>!  OK, that's good.  Lots of common entry points,
and apparently common port numbers.  That's a good start.  

Too bad the busses are so different physically.  But, I suppose in the end
they both expose the system's address lines, data lines, and a few control
signals anyway.  So... How about a controller on a simple daughter card,
with a mother for the H-8 and another for the H-89?   Looks like I need to
grab a few PDFs... :-)
