As someone unsuredly replied, the Acorn RISC Machine (ARM)
used in the Newton and some British computers is a 32-bit
cpu derived (loaded word) from the 6502. One of its key
characteristics is apparently code size/density. All PowerPC 
instructions, for example, are 4 bytes, so code can be a bit large.
I don't know the ARM instruction set though, though I did a book on
it...
