The Timo Rozendal Logic module is a handy 4hp Dual mutli-mode Logic Gate Module. The top channel has 2 inputs with 3 parallel outputs for AND, OR and XOR Logic Gates The bottom channel has inputs as well, but has 4 parallel outputs for AND, OR, XOR and NOR Logic Gates. Each input and output jack has an LED indicator to show the status of that corresponding jack.
The design is based on the CGS39 by Ken Stone (used with permission). LED's have been added to the input signals and uses 3 logic chips to get a variety of led outputs (with 2 sets of inputs, not 4 as in the original).
