The scoop about forth is that you can implement it in virtually 
no bytes (well, physically too of course.)

The "Open" boot prom on Suns and the various spinoffs from that use
forth for that reason.  It's compact, it can be made machine independent
and there is a standard (several actually) so you don't have to invent
the host plate and the deep water all over again.
