#173150 - I have to agree ... maybe that's not what he meant Responding to: ???'s previous message |
I do believe, however, that he'll play hell trying to get a typical 805x to generate NTSC-compatible video signal, even with the necessary video combiner circuitry. The bandwidth demand is just too high. He'll have to cook up some sort of external shift register and time his MCU to the pixel rate. Further, in order to keep from getting lost in the timing, he'll have to struggle to remain in synchronization with the frame rate, particularly with the horizontal sync and blanking.
Maybe if he gets a fast enough MCU, he can do that, but ... how will he display it? What sort of LCD can he get to fit his $50 budget that will do what he wants? I'd guess he'd be WAY better off with a small CRT, unpopular as those are these days. 12" LCD's with NTSC timing-compatible inputs are considerably costlier than that, and small ones, though I can't prove it, are probably more costly.

| Well, that's what I was wondering. | 01/01/70 00:00 | |
| Did he ever actually say that? | 01/01/70 00:00 | |
