Wurde im Forum noch nicht erwähnt. Habe folgendes gerade gefunden. Braucht zwar einen 15KHz-fähigen Monitor, aber macht alles in Hardware und ist Open Source
ZitatThe 80 column output of the Commodore 128 is the same digital RGBI used by the original IBM CGA graphics adapter. Unfortunately nowadays is quite difficult to find a monitor with the suitable RGBI input. The CGA2RGBv2 adapter will convert the TTL RGBI to analog RGB suitable to be connected directly to a 15KHz capable RGB monitor or to the popular Gonbes GBS-8200 VGA converter. As an added bonus the CGA2RGBv2 can also convert MDA and EGA to an analog format for the enjoyment of all our retro PC friends.
Similarly to the older CGA2RGB-B01, the basic circuit is a triple 2-bit digital to analog converter. The main improvement is the addition of a dip switch to select the mode of operation and the improved power filtering to improve image quality with cheap power supplies.
