The HC11 is a good little chip.  I think it would be more fair to
compare the 8051 and the 6805.  You can get the HC11 with Forth in its
internal ROM, by the way.  Send me mail if you would like the address.
Depending on your application, you might want to look closely at the
HC11's interrupt latency.  It hasn't been a problem for me, but I
believe it's in the 6-30us range.

I just recently put the finishing touches on a controller for a variable
reluctance motor, and I used a 68HC11 in the design.  And you're right
about Motorola having a lot of good stuff for it.  I believe they
recently added a real-time kernal.
