Die Gruppe comp.robotics.misc in englischer Sprache wäre geeignet.

Schade, dass Forth von Hempel für Lego Mindstorms nicht mehr
vorhanden ist.

Ralph Hempel switched to Lua. This is the result of Lego's next
generation robotics kit – the Mindstorms NXT. Inside the NXT brick is
a 32 bit ARM7 microcontroller with 256K of FLASH and 64K of RAM.

Ralph Hempel was asked as expert (http://www.wired.com/wired/archive/
14.02/lego.html), and he discovered Lua, he writes (http://
hempeldesigngroup.com/lego/pblua/about/).

I read somewhere that Lua is related to Forth.

Not at all. It's more related to Tcl. It's said to be "small", with
120k being "small", haha.

Unfortunately, Ralph Hempel promised in 2009 to release the source code
"shortly", but so far, nothing happened. I gave up porting Gforth to
the lego brick, because enabling all the communication stuff you need
(USB and Bluetooth) was too much work, and too little documentation and
examples were available. But Ralph had done all that, though, as the
source code is not available, inaccessible.

Hm, maybe I should kindly ask him per e-mail.
