[Coco] Coco 1 & 2 differences

[Luis Antoniosi (CoCoDemus)]

speaking of CoHR i made a patch to it. So now it understand OS-9 cursor
codes intead of its very own esc codes. It runs fast because it understands
the cursor on/off codes too. In fact i implemented all os-9 codes.

Now i can run minted on it :) too bad not enough memory is left to run
dynacalc :(

seems most of the people are coco3 and nobody cares for the coco1&2 :'(
