assembly language simulator

[Chris ALPAUGH]

Has anybody out there ever written any sort of assembly language simulator?
I'd be interested to know what sort of algorithms and techniques you used
to decode the instructions.  This is a limited project, so I'm not going
to attempt to write an entire assembler, but just a program that will accept
assembled PDP-11 code and "run it", in a simulated environment.  Any info
on this sort of ting would be greatly appreciated.  General algorithms and
ideas would be great.

thanks in advance, Chris
