 I sure that there was a FIG-86 listing done( would run
on a 8088 ). There is also a large Forth that runs under
DOS called FPC that is available over the net. For those
that want to create there own smaller '86 Forth, there
is a tool called TCOM ( by the same author ) that creates
COM files. Since these are just code, they can be made
to work on any '86 compatible platform. With minor changes,
any target processor can be used( I've used it to create
8051 and Z80 code ). As I recall, the release comes with
a number of examples of targeting for other machines.
 It was mentioned that a Forth could be as small as 32K.
I've done quite a few that run in less that 8K of space
( 6K ROM and 2K RAM ). If one doesn't need the interpreter
and compiler, 2K systems are quite practical for many
applications. These are often done as tethered systems
where something like a PC has the compiler and interpreter.
The application machine only needs a way to read/write
memory, execute and break execution.
