Intelligent Systems Corporation owned both Compucolor Corporation and Intercolor Corporation.

The Compucolor II had different video hardware. I'm not sure if the systems are mutual compatible for binary software. I mean, they are fundamentally different designs.

The Compucolor II was made to directly interface memory with keyboard and video hardware, more like a modern system, rather than sending and receiving serialized data between external hardware. Also, the video was hard coded in the ROM. I'd have to guess that this is a compatibility issue. BASIC 8001 was available for both systems and generally cross-platform, except for having different graphics and text resolutions. And Compucolor Corporation released separate versions of their games for 8001 and II
