Smaller? Sergey and I were discussing making the kernel a bit smaller, but
so far my 10x10 maze robot takes up about 4K out of about 13K of application
space. With better coding, I could probably shave about 1.5K off that.

I find it hard to believe that anyone could use up the space in the RCX
easily. 13K is a LOT when you are doing a really embedded system...

Try and write some code for pbForth or LegOS and see how much memory
actually gets used up.

Sorry if I seem like I'm ranting, but I want through a similar
phase in actual Technic construction. If only I had this or that part
then I could build X. In software it's the same thing. If I had 256K
of RAM and  floating point processor, I could do neural nets.....well
the RCX has VERY limited processor power and RAM. I still
think it's an amazing little brick and challenge anyone to build
and program a practical bot that uses all of the memory.
