Discrete Logic Gates

** 4U Modular is a term used for the format most commonly known as “Serge Format” or “Loudest Warning Format”. Out of respect for the ever growing format, 4U Modular is the easiest way to refer to it. More Specifically it refers to the panel height and mounting hole style. 4U Modular will patch up just fine with other 4U "Serge" formats such as "Random Source", but it will not mount in RS boats or Buchla Boats (or power off Buchla power for that matter). An info page about this will be added to the website soon to make this a lot more easy to understand.

DIY Build Information: V1 pcb building… there is a board error where one leg of Q17 isn’t grounded and leaves AND output at a Logic HIGH.. To fix this, simply run a jumper or scratch the mask off the ground plane and connect Pin 1 to ground.
