Adds eight pushbutton inputs and eight LED outputs.

The current listing is a complete kit, with a bare PCB offered through the vendor's grouped PCB listing.

Adds eight 5 V TTL inputs and eight 5 V TTL outputs with state LEDs.

The project supplies a schematic, Gerbers, PCB design files, and kit or bare-PCB paths. PCB v1.0.0 leaves insufficient space for C5 to sit tight against the board; this is fixed in PCB v1.0.1.

Adds eight remote input switches and eight output LEDs for RomWBW or an Orton 3C.

The current kit has different LED, bezel, and resistor options for RomWBW systems and the Orton 3C. The bus-extension socket carries Standard Bus signals and up to four Enhanced Bus signals but is supplied unpopulated.
