Yup, this is cool. It struck me that this is just an ol'
i486/66MHz. I'm just tinkering with little SBCs that are
486/133MHz. They are very small. With those you could build
a miniature PDP-11. That way you could have all the fun
(and blinkenlights of course) in much less space, portable,
PDP-11 to go :-)
