Logic labs, but who cares about that.
_I_ care about it... I had the manual for one when I was about 12. I
learned digital logic on paper from it. I always wanted one, but the
books were much easier to find than boxes.
Every once in a while, I entertain making one of my own, but haven't
ever come up with an inexpensive and robust plug/connector scheme.
The more interesting thing is a
book for the CDC logic trainer. From the pictures and writeups in the
manual, this box has no logic of its own, but is made to accept a
small number (20) of logic cards from a 1604. It mentions that it can
be lightly modified to take 3000 series cards as well.
That _is_ more interesting. I am also curious to learn more.
