Me too, except that Forth gives you ample opportunity to hang
the machine with infinite loops and errant pointers causing writes
into the program space.
On the bright side, I have been working on a trap handler for pushbuttons
that will give us most of what we need. More on this in the next few weeks, I
hope.
See this article for hints on how to hook into the 1 msec timer...

SEE would be great to add. If you can find a version that is ANS compatible

h8300/rcx/pbforth/pbforth.tcl - describes the files used in pbForth

Cheers, Ralph

| From my experience, what you are describing is normal behavior for the current version of pbForth. Mr. Hempel has done an excellent job of creating a version of Forth to work with the RCX, but the work is far from complete. If you look at the (...)
