Some useful circuits I've been collecting over time. All of them, despite being very reduced in size, make use of very clear concepts, without any form of "dark magic".

  @LogikMacherDE: an I/O port is just wires, what makes it I/O is how it is used inside a larger circuit. @That_PowderToy_Guy: they are 1-to-N and N-to-1 "routers", so to speak. Signal goes in or out a wire in the (DE)MUX, and which wire is used is chosen by the addressing on the bottom. The "clear" pin is for clearing the address. You can use that to connect multiple devices to the same bus, for example.

  @Mandarino1091 you can use the latch with increment for that. If you want to make it smaller, you can remove the parts that do the increment, if you're not going to use that. You can also use the pseudo-d-latch to store a single bit, but you have to replace the NSCN with INST so it doesn't reset with every read. Then you can stack eight of those to make a byte.

  @Makerbenjammin6: dark magic = subframe and stacked stuff -- @Rubidianlabs maaaaybe, i only updated this to make the ae letter prettier than it originally was hahaha
