It uses LEDs for display. See the 8-bit data and strobe signals coming from the keyboard. Watch the strobe signal going high to low (or vice versa). Additionally, the reset and clear signals can be tested for the Apple-1 and Apple ][.
The board needs a 5V power supply as a minimum, but some keyboards need -12V and/or +12V to operate. Onboard is a passthrough power out connector for the keyboard. Connect an Apple-1 or Apple ][ keyboard directly using the DIP-16 connectors. The extra data-in connector can be used to connect uncommon or custom keyboards.
The One Byte Hex Display is optional. Display the hex value (two digits, 0-F) of any parallel 8-bits TTL input. Mount it on top of the ASCII Keyboard Tester, or use it stand alone. The jumper can be used to enable (or disable) the 8th bit. Using this jumper, both ASCII values (7 bits) and full bytes (8 bits) can be displayed correctly. The board needs a 5V power supply when used stand alone.
