MIPS support

Actually, how difficult is porting Self to a different architecture?
It'd be nice to be able to get it running on more machine types.

And, in a similar vein, is their a version of Self for SunOS 3.5 on a
Sun 3?  I sit in front of a machine which claims compatibility with
that OS, and it'd be *really nice* to be able to run Self on my own
machine.
