That is AWESOME!
I had the Coco as well - loved that machine. I think I also had the upgraded one (Cooco2 or 3 - can't remember - white case, compared to the original grey case).
Funny you should mention theold school Flight Sim...I have in my closet a Commodore Vic 20, C64, and C128. I also have SimLogic Flight Simulator II for the C64 here
Cheers!
