No, it's way simpler than that. The text files on the Palm are source
code for Quartus Forth on the Palm. The idea is that the *same* source
gets sent to the RCX via the IR link - you can do it now with a serial
link, a terminal emulator, and the IR Tower.
pbForth takes human readable ASCII source and compiles it right on the
brick. The pbForth firmware does all the compiling etc. In todays world
of C Development Studios that span 2 CDs, putting a compiler in a 14K
image seems impossible, but that's what pbForth does, and it's fat compared
to the early Forths. I'm working on a slimmed down compiler with less
error checking that takes only 8K!
