Brainiac
The Brainiac is an 8-input logic module with 8 different logical gate outputs.
It has all the classic logical outputs (AND/OR/XOR) and their opposites (NAND/NOR/XNOR) as well as a Majority and Minority output which go high when more or less than half of the used inputs are high.
Input Tracking
Unlike most logic modules, the Brainiac keeps track of how many cables are actually plugged into the front panel. Some of the logical outputs will have different states depending on how many cables are plugged into the inputs.
The order of inputs does not matter, all 8 inputs are interchangable.
Classical Logic Outputs
AND/NAND
AND goes high when all of the used inputs are high. NAND goes high when not all of them are high.
‡These functions are based on how many cables are plugged in
OR/NOR
OR goes high if any of the inputs are high.
NOR goes high if none of the inputs are high.
XOR/XNOR
Majority & Minority Outputs
Majority goes high if more than half of the used inputs are high.
Minority goes high if fewer than half of the used inputs are high.
Neither of these outputs will trigger if Exactly half of them are high (the half output is available in and upcoming expander)
e.g. If you have 5 cables plugged in and 3 or more of them are high, then Majority goes high, if 2 or fewer are high then Minority goes high.

Turing Machine Integration
Using the Brainiac as a Turing Machine Expander
The Brainiac can be plugged into a Music Thing Turing Machine MkII as an expander and the 8 gate signals from the Turing will route to the 8 inputs of the brainiac. When it is used in this mode the Brainiac inputs can still be used and are "diode summed" so each input can be triggered by either the Turing or the Brainiac input.
Using Turing Machine Expanders on the Brainiac
The Brainiac can also control Turing Machine expanders without a Turing Machine. In this case Turing expanders like "Volts", "Pulses", "Voltages", and "Vactrol Mixer" will accept the 8 inputs of the brainiac in lieu of a Turing Machine.
In this case the input numbers on the Brainiac actually matter since the Turing Expanders care which of the 8 gates is high.
Expansions
There are two expanders available for the Brainiac
Binary
This expander exposes the number of inputs used and the number of inputs that are high each as a 4 bit BCD (binary coded decimal) you can use this to make some funky rhythms.
Explicit
This expander derives all of the other logical outputs I could think of and it is what truly makes the Brainiac an Omni-Logic Gate. It outputs Half, !Half and Equals X, !Equals X, Less Than X, and Greater Than X for each number 1-8.
Analog Computer
The Brainiac is all CMOS and has a lot in common with old analog computers. But since it has no clock or microcontrollers it does not wait for a clock pulse to calculate the output and can run at audio rates to make logical drones.
