It would be nice to use this DOS. I did take a quick look at it last week,
but didn't find out how to use it (start CONTIKI.COM after booting).

I didn't look further into it b/c I thought MyPicoDOS would use even less
memory. (There is a comment in the source where it copies the load routine
to $80 and runs it from there, but I later found out that this is only
done for boot image loading.)

So how does one load programs from 3sdos?
