[Coco] CUBIX on the CoCo?

[jdaggett at gate.net]

Hello Dave:

As far as I know no one has ported Cubix to the Coco or at least the 
Coco 3. I looked into doing a port to the Coco3. Several areas that 
would require a deal of work. Since there are plenty of Coco disk 
controllers availble to most Coco users, the disk driver would have 
to be written for the WD1793/1773/2793 chips. Also the I/O range 
moved to $FF00-$FFEF. Finally there is the GIME chip on the Coco 
3. 

While not impossible, it does entail a bit of work and time. Thanks 
for  the link as I too  have an older copy. Maybe I can look at the 
latest and see just  how complex a task it will be. Currently I have a 
major home project working now that is taking up a bunch of my 
free time.
