the above site is also interesting for the
"3-instruction Forth for the 68HC11", an FORML article
- 3 instruction forth:
How many instructions does it take to make a
Forth for target development work? Does memory
grow on trees? Does the cost of the development
system come out of your own pocket? A 3-
instruction Forth makes Forth affordable for target
systems with very limited memory. It can be
brought up quickly on strange new hardware. You
don't have to do without Forth because of memory or
time limitations. It only takes 66 bytes for the
Motorola MC68HC11. Full source is provided.
The absolute minimum the target must do, it seems to
me, is fetch a byte, store a byte, and call a subroutine.
Everything else can be done in high-level Forth on the host.
