Yes, its been asked. I think here. There was even discussion of reproducing it. The first consensus was that a 512k board would be needed, no way to run it on a 128k with how little RAM it had.
I think the conversation also discussed the custom video out card created to have the Mac display the demo on the large projector.
Well, its one of those things that at the time seems like just another piece of hardware, with no one knowing how truly significant it would end up being, and how valuable it would be to preserve it for posterity.
I actually totally understand why the owner will not share. It would just become commonplace software. Right now its unique. Thats the problem with software, too easy to duplicate.
Well at least show it booting and doing its thing, and put it on Youtube. It's like having a vintage Ferrari that you don't even look at, let alone anyone else. I get not sharing the file, but at least share the routine with a modern HD recording.
In fact, the value of its original is huge for now, one day we'll probably see en auction on ebay at outrageous starting price... Maybe the next owner will be more selfless and share if not a disk image, at least a youtube video of it
what came first the chicken or the egg? I'm sure the IWM… WOZ being the smart cookie he was… had DCD type thing in mind, after all it is supported in hardware.
