Building a 68000 Single Board Computer - Top Level Schematic (schematic page 1)

See https://github.com/jefftranter/68000/blob/master/TS2/v2/ts2.pdf

Each IC has a 0.1 uF ceramic bypass capacitor across the Vcc and GND pins. A single 100 uF capacitor provides additional power supply filtering. It requires a +5 volt supply. A switch controls power and a green LED (D2) indicates power on.

The majority of chips are 7400 series LS family TTL devices. There are a few spare gates. Their inputs are grounded as per standard TTL design practice.
