Thanks for looking at my working C128CR 

This board is exceptionally rare and there is very little information available as to the origins of this mainboard.  I have only ever seen mention of it a couple of times, mainly as an "engineer sample" or "prototype board"

I contacted Bil Herd the Commodore designer of the original Commodore 128 and even he was unsure http://c128.com/c128cr

The board runs with an 64k VDC chip and an 8580 SID 

This has been part of my collection for a couple of years and I have decided to get rid of everything that I dont use frequently. 

The pictures of the board are missing the SID chip but this is now included (shown in the video link) http://youtu.be/Cm4hU7yuxyk

You are bidding for just the C128CR board and case.  There is no power supply included.

Forgot to mention... This is a PAL model
