I have another RGBI to RGB analog interface for Commodore 128 for sale. The interface connects to the VDC monitor port of the C128 and can provide either RGB or monochrome composite picture. The interface is based on H2Obsession's RGBI to S-Video schematic. I've adapted the schematic on veroboard and adapted it to be connected to a Scart connector. There are extra rails on the board so you can either provide CSYNC and blanking for scart or HSYNC and VSYNC for VGA. You'll need a multisync monitor or scan doubler in between with VGA. The VDC port doesn't provide blanking or sound. If you need blanking and sound, you'll need a separate cable from the video port.

This interface has slightly different resistor values to provide a brighter picture. I've tested the adapter to work on my C128 connected to the TV via Scart.

Price is 12 (was 15) € including postage. Payment by Paypal gift or buyer pays fees. Cables are not included. I'll provide the pinouts to help you making the cables.

Note: While I can provide advice and info in making the suitable cables, it's not possible for me to actually make the cables for the interfaces. You need to make or source the cables yourselves.

A little progress update. I have 2 veroboards cut and made ready. I'll make a status list on the first post that will be updated. Bluecursor, did you want a second one?
