   I really, really like FORTH.  Any old SPARCstation makes a great 
FORTH learning vehicle (OpenBOOT), but I opted to build a small Z80 
single-board computer and ported Brad Rodriguez' CamelFORTH to it as a 
machine on which to learn the language.  I've had great fun with it, 
and the language is VERY powerful.  I've extended it quite a bit; 
written a full-screen editor, drivers for new hardware (I2C flash, VF 
display, I2C tone generator, etc) etc etc.  I hope to add analog I/O 
sometime soon.

   I have a few Harris RTX2000 chips (essentially a native FORTH 
instruction set...very neat) but haven't done anything with them yet.  
I really need more free time.

   Brodie's books are good; they will serve you well.  Here are some 
URLs to get you going:
