It is one of the things in which academical training is perverse. It trains you to always complicate more and more any subject, and that the hard work is the goal, shortcuts are not permitted.
- dmitripopov 7y agoI agree. But, you know, enthusiasts enjoy holywars. And there's a thin hazy line between a "true" and a "cheater".
- glouwbug 7y agoWhat was the hack? PWM to an RC filter?
- Cyberdog 7y agoI believe it's the one mentioned in the article about how to achieve a color NTSC signal by just outputting ones and zeroes with proper timing. It begs the question what was done in parts of the world that didn't use NTSC, though.
- fsckboy 7y agothe other video standards (Europe used PAL) aren't much different in principle than NTSC, just some different timing and encoding parameters, the same D to A techniques work. PAL is higher bandwidth (and higher quality) than NTSC and Woz's timings were on the edge for NTSC so PAL versions didn't do color till a little later.
