Ah, Lisp machines.  Been a long time since I saw one of those.  ATC 
trainer project that I worked on in college was built on one of those 
things; one of the geniuses (seriously) who worked on that code explained 
how on the system we were using he could change how the instruction 
pointer ran and break the machine.

Pretty incredible piece of hardware.  Can't remember who made it, 
timeframe was the early 90's.

Architecturally they're fairly different, though.  Depends on what 
aspects you want to study, and how much access you have to the underlying 
code (with Windows, there is an academic source license available IIRC).
