>The Logi-Tran 4 was the follow on to the Logi-Tran 2. I used both to
>teach EE370 in 1979 or 1980. As you've no doubt learned by now, it's
>basically a "50 in 1"-ish logic trainer with spring connectors, switches
>(inputs), lights (outputs), and of course, the logic ckts themselves. It
>was a great trainer for our digital lab (I was the TA).

>I remember making a 4 bit calculator with one of my more talented students

>by side.

>If you've let it sit because of the lack of a manual, just start setting
