I have similar tales of playing "Lunar Lander" on an ASR33.

Which is why this little baby is so cool. A microprocessor with 
enough muscle to actually DO something, yay!

It's typical that all the problems of the last 40 years of computer 
development are being played out with the Basic Atom in 
miniature. Compiler upgrades that won't compile old code, typos 
in the compiler. Fixing something and breaking something else 
etc etc. etc.

Thanks for taking on the heavy lifting for the MIDI ISR. I'm getting 
the Joystick Axis Generators made and don't have time right now.

I hope to be back to it soon, with some cool software, now that 
there is math in the dev package.

Thanks again!
