This is wierd. I had it working on my Caldera Linux 2.2 which has TclTk 8.0.4
I'll try again. One of the problems is that I can't seem to get a nice NFS
system running here, and I have to FTP the files around... :-(
I'll try and make a better tarball with the permissions set (hard to do
under WIN) and I'll fix the shell startup too!
Thanks for the effort of debugging this stuff, any pointers on installation
and running this under Linux are much appreciated....

The delete firmware did not work. I guess I should mention that
you need to start the RCX up fresh - it does not reload the firmware if
pbForth is already running....

How are you "seeing things in the window" The SREC download sends
a rather complicated sequence of complemented bytes to the RCX.
It's getting a binary image, not an SRECORD file.

On Kekeoa's internals page there is a link to the source of firmdl.c
Not too many people need to know how it works, it's easier to use
firmdl or nqc...
