Regarding Supervision development, the following information has been provided to me:

I saw a Supervision development system. It consisted of the bottom half of a Supervision console (i.e., the controller), connected via some wires to a large PCB. This PCB in turn connected to a card in the developer's PC.

Unfortunately I will not get a chance to test out this development hardware, but I did get some of the development *software*, which is quite interesting. The Supervision uses a 6502 processor, and a colour version was at least planned. Maybe the released console supports colour graphics internally, but just uses a monochrome screen. I say this because part ot the development software included a Supervision emulator, which runs in colour on a PC. I only have one test ROM image for this emulator though.
