Hi Gene,

Yes, I was just curious that he managed to compile Unix V7 utilities to 
run under it.
There didn't seem to be much in the way of source code.
I was wondering if I could write a multi-tasking kernel for it that 
supported extended memory.
OS9 is OK. It just seems to do things a little differently to UNIX in 
places.

John.
