I have no interest in NES, I have no interest in MSX, I have no interest in Apple II. I have an interest in C64.
I already have two C64 machines, three if you count the dud C64GS.
I have no interest in buying this proposed machine. I'm not sure how many people would be interested at all really.
I love to hear ideas, but this doesn't seem a good one. Don't take it the wrong way, you'll come up with something better I'm sure.
