RWeick/REF1011-Sega-GameGear-Pro-Action-Replay
The JEDEC PAL dump, ROM dump, and Kicad PCB files for the Sega GameGear Pro Action Replay.
Boards in 7 GitHub repositories, designed in KiCad, that use the SN74HC32N by Texas Instruments (-40℃~+85℃ 1.5V~4.2V 17ns@6V,50pF 1mV~100mV、150mV~260mV 2 2V~6V 2uA 4 5.2mA 5.2mA 5.48V~5.8V、5.9V~5.99V 500mV~1.8V 74HC Series OR Gate DIP-14 Logic Gates ROHS). See how each wires it, with its parts, size, README and files; the SN74HC32N’s symbol, footprint and pinout are on its own page.

PhdWizards/4-Bit-Discrete-Transistor-Adder
The core 4-bit binary adder is implemented entirely using discrete transistor-resistor logic. The resulting 5-bit binary value is converted to BCD using 74HC-series logic and displayed on two 7-segment displays.
