This was a question I posed to the net some time ago.  I was surprised
at the number of skeptical opinions including one fellow who had a hand
in designing the MC68000 family.

I know of at least one 64-bit microprocessor in design in Japan.  I
don't know much about it, Lucius.  I decided to post a followup rather
than send mail because I have a similar question: does anyone on the
net know anything about a chip by Hitachi with the designation of H16?
It's my understanding the H16 has a vector instruction set complete with
chaining, and a vector/cache like an H-810/20 super computer or a
Fujitsu VP-200/Amdahl-1200, except that it's a 16-bit micro.  Not
64-bits, it it sounds impressive just the same.  I would appreciate
details.
