Commodore 128/ CGA Video DAC Board Available

I just completed a new build of Richard42's fantastic Commodore 128 video DAC board.  This is a fantastic little board that, in combination with a Gonbes GBS-8220 arcade RGB scaler, produces great 16 color, with intensity, output on any modern VGA monitor.  To boot, the combination also works great with IBM CGA or low-res EGA cards!

I did two rounds of prototypes, and the following is what the final board looks like.  Please excuse the poor quality of my living-room photos.

I am now making these available to the vintage community for the price of what the components cost me, plus shipping.

If you would like to purchase one, I am offering several different ways to get it.

Please let me know if you have any comments. I'll work on getting some screenshots, as I was referring to some posted on Commodore128.org, but that forum seems to have gone down, rather unexpectedly.

  2. Yep. I just stopped building them, as I don't have the spare time. I can sell you a PCB or a kit.

  3. The kit version is fine. I've been kit building and scratch building for about 50 years, si I think I can handle it!

  6. I'm going to discontinue availability of the kit, for now, as my daughter was just born. I hope to continue availability, in the future.

  10. Dominik,

    I haven't received any orders from you. Unfortunately, I am not accepting orders, at this time. I will post, again, when orders can be fulfilled.

    Thanks!

  13. Do you have dimensions for this board, or a drawing with measurements? I've had a couple of requests to build mounts for it for my Commodore 128 VGA Module enclosures.

  14. wfp,

    The board design is available, through OSH Park. Go to https://oshpark.com/shared_projects/9MPsJlrJ to see it. You can get the dimensions from there.

    Good luck!
