From the project

Bare-metal Raspberry Pi project that provides pixel-perfect sampling of Retro Computer RGB/YUV video and conversion to HDMI

This is an adapater to be plugged between the VIC-IIe and its socket in a Commodore 128. Using this the, C64 Video Enchancement Board should in theory be able to work for the 40 columns mode display of the C128.

Use the provided gerber files (gerber.zip) to have a the PCB manufactured. Use the provided bill of material (c218adapter_bom.ods) to order the necessary parts and solder everything according to the silk-screen placement markings. Be careful to get the orientation of the various ICs right. Pin 1 is always marked specifically.
