CL kits. These were computer educational kits. The
basic module was a
plastic box with 3 input sockets, one output socket (with a lamp to
monitor the sate) and 8 'programming' sockets. By wiring up the latter
appropriately you could get the module to act as any 3-input gate. If
you wanted a flip-flop, you could either corss-couple 2 modules, or feed
the ouptut back to an input on the same module programmed as an AND-OR gate.
I assume this is transistor not relay logic.
Alas the smallest kit (all I have) only contaiend 2
logic modules and one
battery/input switch module, whuch wasn't enough to do much with.
That was the problem with all the computer trainers, they were too
small, even the ones with a cpu in them.
