From the project

Keyboard adapter for the neo128 project to use with a standard c128.

A tiny crossover PCB that lets the [c128-keyboard / the-c128-keyboard-project] mechanical keyboard plug into an Open128 motherboard (or a stock Commodore 128), whose keyboard connector uses the original C128 keyboard pinout.

The mechanical keyboard board terminates in a 26-pin FFC (CN2, Molex 200528-0260, 1.0 mm) whose pin order is not the original C128 order. Open128's keyboard connector (CN5) is a DSUB-25 footprint carrying the original/stock C128 keyboard pinout. This adapter remaps one to the other on copper.
