I saw that stuff in the early 80s and couldn't come close to affording it.
Fischer Technik has gone down spectacularly since I
was a kid. In the old
days there were fairly simple elecrronic modules (alas so expensive that
I couldn't afford enough of them) -- things like a double pole changeover
relay, analogue voltage comparator, AND gate, OR gate, flip-flop,
monotstable, etc.
I remember that stuff - in particular, I remember enough logic for an
elevator controller and a traffic light.
I'd _love_ a way to home-brew some sort of snap-together logic toy.
For that matter, I'd love a way to make something like a DEC Logic Lab
from stuff around the house (i.e. - a 2 sq ft board
covered with logic
and plug points)... One could use banana jacks, etc., for the
interconnects, but at retail pricing, that would start to add up to
real money real fast.
