The video board takes the luma signal from the 64 and splits it into the h-ysnc, v-sync, and video signal expected by the PET monitor, but anything other than black is shown as green, so you will only get true monochrome images such as these: Very interesting! I didn't know such a board existed. Do you know if it works with the 9" PET monitors or with the 12" ones? And with PAL or NTSC C64 or both? > http://inchocks.co.uk/commodore/4064/4064_BoulderDash.JPG > > AFAIK, no-one has found or reverse engineered a schematic yet. well, maybe if a copper side image existed too, I might reverse engineer the schematic :) FrankReceived on 2020-05-30 00:09:14
