TMS9918 VDP technical specs (~), cannabis (+)
At nearly midnight, I find myself stoned whilst attempting to puzzle out the logic of the color palette of the video chip from 1979 that appeared (along with minor variants) in so many game consoles and home computers, including the TI-99/4A (my first!) and the ColecoVision.
This is mildly complicated and involves NTSC signal generation, I think.
Alas, I have erred! The weed only feeds the desire to comprehend, not the ability! *doomed*
