[Coco] Reading keyboard input without basic

[spereira1952 at comcast.net]

I would suggest consulting the "unraveled" series of books available here: 

http://www.colorcomputerarchive.com/coco/Documents/Books/Unravelled%20Series/ 

I believe that "Color Basic Unraveled" will reveal how the Color Computer performs its console I/O, and you can build up from there. 

Good luck!

Thanks for the info all. Does anyone have more info on the available rom 
routines and maybe an example of using one in assembly ?
