CUBIX/6809 updates

[Tom Uban]

Cool Dave!

Is this running on other hardware than your homebuilt 6809 machines? Can
you please describe the Cubix features (disk?, commands?, etc.)? Or should
I just RTFM...

I wrote a ton of 6809 assembly when I was programming pinball machines
at Williams/Bally in the 90's.
