To start the journey of discovery, we must have all the building blocks and tools ready to use as creativity requires a selective group of useful mechanisms to achieve a modicum of feed back to keep the momentum going forward towards interesting and useful discoveries. The Ternary building block are here, along with a Binary controller that you can use to design your Logic elements as needed. I have shown previous Unary gates and they are still usable in these designs. I decided to put 4 gates in one unit so wiring can be simplified when you create the 2/3/4 input gates. For a 2 input gate you need 3 gates for the columns and a summing gate and 3 gates for the rows a summing gate for the rows and the result. This makes it simpler, you will only need 2 unary boards for an 2 input gate, a base board was designed to make this easier, these can be stacked, as high as required.

TMS9995 SBC
Each Unary board consists of 4 separate Unary Gates they can be used as a set or individually, depending which base board you use.
The Unary Gate Base Board has been configured as a 2 input gate A, B and the result in C.
The Unary Gate Base Board Singles is configured to use as either a 2 input gate by wiring it as
required or as single chains or groups.
J1, J4, J7, J10 are your ternary inputs, while J2, J5, J8, J11 are your outputs to each gate.
K1, K2, K3 are configurable with J40, J39, J38 as a matrix to give you all 27 Unary configurations.
The interconnections are configurable with a small 6 pin cross connected board, or you can use jumper cables if you choose.
Controller Board
This has a 12vac input and 18+3 pin binary input and a 3 pin ternary output. It was designed to connect to a TMS9995 SBC with CRU outputs and have software to control the gate configuration in hardware.
With Five Boards there are 45 binary controls which will give you a Ternary Multiplexer made of five 2 input gates and 3 Unary gates. Once you have tested and configured your logic, then you can use the base board with plugin matrix connectors as your final gate design.
Setting Your Bits
H1, H2 and H3 are your binary control bits to select each gate type. You select 6 bits to as either decimal or Hex to each unary port. I added U28(74LS125) and U29 3 pin header which is used to switch each gate on, under software control as required.
Ternary Input Switches
This board has 9 ternary outputs and can be used to control the A+B inputs on the Unary boards.
There is 9 RGB indicators for the slide switches, Red = +5v , Green = 0v , Blue = -5v.
Ternary Bit Display
This small board gives you a visual indication of your output bits,
Red = +5v , Green = 0v , Blue = -5v
Listed below is the Program to control the Ternary Gate Selector. If you want to attach more Selector boards you will need to expand the CRU outputs. I have left the header J5 to allow CE for more TMS9901 to be added at some point. The next version will also have have mounting board for 4 more chips, giving a total of 96 outputs.
Where 21 are needed for each 2 input gate, this allows control of 4 2 input gates, 84 pins , leaving you 12 spare pins for other controls.
This is a Cortex Basic program to control one two input gate.

Here is the layout for the SBC and the Ternary Gates.

An alternative design without the SBC and just putting units together.

Here are a few pictures regarding some of the components.

This is the CODE for the 27 selections of Unary gates, H1,H2,H3 CRU outputs.

Here are the PCB’s for the Basic boards.
