[Coco] List of programs

[Barry Nelson]

 Does the CoCo 2 you have support the semi-graphics 6 mode (I think it is called)? It was present in the CoCo 1 and removed from some later production run CoCo 2's? If it has that then for all compatibility intents and purposes I am aware of, it is a CoCo 1 with 64k. If not then it is not compatible with some CoCo 1 programs, like the Appliance and Light controller rom, which does not display correctly if this mode is not present. I am not aware of any programs I can think of right now that run on a later model CoCo 2 (without semi-graphics 6) that do not also run on a CoCo 3, however some of the CoCo 1/2 programs require an NTSC composite display to display color. It is certainly possible that there are a few programs but I don't think there are too many that will run on a late run CoCo 2 that will not run on a CoCo 3.
