Oh course, you may need an upgrade for that There's a question. Why? It seems to be a pretty useful unit for a COCO, so why are they hard to find? BTW, am I going to need a MP to use the hi-res box? How does it interface? Can I use the old "Y" connector I used on my COCOMAX I hi-res pack? As for controllers, how do I "spot" an "old" controller? I saw various differences along the way, from the pack getting shorter, to the change in color from black to white, etc.. The ROMs in the first "old" one were 1.0, mine's 2.0. Does that make mine "new"? Or is the shorter case the result of the 12V components being eliminated? Again, I don't have "new" pack available to swap, and I'm not sure I want to spend a couple hundred putzing around. And also-again-in-addition-ad-nauseum, the disk basic prompt comes up, the drive is activated, but no files are found. Maybe that's a clue to something, but I'm not sure what. It'd be simpler if I had a new controller to swap, but I don't. Lastly, why are COCO-IIIs so cheap? Cheaper to produce, on the way out, or is COCO-IV coming out? Any guesses? GMS
