Chuckle, as usual Andy, you place the state of our art in its proper perspective. I am reminded of Art Clarks statement about technology vs magic. To the ZX-81 owner, that is indeed magic, black even. ;-) I had one of those with the 16k ram pack, in about 1979. My kids wiped out the chomerics keyboard in about a week. So it wound up in a slope topped steel box with what may have been a TI-99 keyboard cut into the top of the box. 99.9% empty space in the box, but the kids were happy and still remember it today.
