For the first two, I'd recommend you visit Robert Gault's website and download
his SYMMETRY program, which has source code you can study.

For #3, search RTSI for HIRES.ZIP(I think) which has code to read the Tandy
Hi-Res joystick driver.

Also, consult the Unravelled series for details on how *everything* CoCo works.
