We got one (no keyboard) a couple days ago with the manual. I'm still
cleaning it up. It had something nesting in it and
the inside has sunflower seed husks in it. It was made with plastic DIP
ICs, no idea of the logic family. The keyboard
was made by IBM, don't know what character code it produces. Pretty funky
if it encodes ASCII.

, which is showing a 404.
