failing to hear about another version of a 6811 emulator, i wrote one
last night (and part of sunday night).  it is still rough, has no user
interface, doesn't do multiply, doesn't count cycles for all
instructions, doesn't let you modify memory or registers and doesn't
support the semantics of the $1000 locations at all.

what it does do right now is let you load a file in s19 format and
single step it.  adding the missing features should be relatively
trivial.  i am sure that there are some (several?) instructions that
don't work correctly, and that there are probably other problems as
well.   it should also be absolutely trivial to port to any machine
that supports ansii c and 32 bit integers.  ansii c and 16 bit ints
should be an easy port.  there is a relatively large (2000 line) case
statement that might give some compilers fits.

this software is not ready for prime time, but i would like to find
somebody who is willing to trade early access for testing and possible
mods. 


any takers?

If there is enough interest (ie beyond myself), I would like to port
this to the Amiga and give it a nice GUI.  Any thoughts?
