[Coco] RE: CoCo 4 - the dream continues...

What would be the minimum level to be considered a Coco 4?

It's tempting to develop an interpreter that could load coco BASIC  
programs, either from hard drive or a genuine coco disk. This would  
have to detokenize each file and emulate the display from the  
original coco. After that, it sounds trivial to enhance BASIC by  
adding new features such as enhance resolution, multiple windows, and  
sound. (Assuming built on Windows/Mac or PC hardware.)

I'd like to see a coco board to install into the PC. This would be an  
expansion card with a 6809 cpu and a modified rom that allows the  
original coco to run in a window. (Has this been done?)
