Depending on the computer and software used, it does. Hmmm, sounds like a phrase that might apply to me, but I'm not familiar with it. I own a copy of the book "Tools and Their Uses" and have managed to avoid ever reading it :^) Zane

Wow, if that's worth $5000, I wonder what my QDOS floppies and Seattle Computer Products S-100 must be worth? Probably nothing, as I'm sure he'll get no offers at $5k. Tim.

I'm not sure what's up. The Canopus can't even do PAL as far as I know, and I'd used it earlier that night with a definite NTSC signal. As far as I know the IIgs is NTSC. To make things even stranger, when I booted up a System 6 floppy, I got colour once it was running the GUI, BUT, it was a bit distorted and not the most readable. I've been doing a little work trying to get a spot cleaned up to set it, and the monitor up, though, I seem to be having a bit of a problem finding a spot to plug it in. Zane -- -- | Zane H.

No, the IIgs has color on the composite output. Perhaps you're thinking of the Apple III, which did not. The IIgs uses a Motorola MC1377 color video encoder chip to produce composite color video from the RGB outputs of its display chip. The normal video output of all Apple II models does not really meet NTSC spec, so some devices will have trouble with it. In particular, each horizontal line is supposed to have exactly 227.5 cycles of the color carrier, but in an Apple II it takes 228. If you have the video overlay card, that produces proper NTSC output. There was an amazing hack for the original II/II+ to generate broadcast-quality NTSC video. It was a product from Video Associate Labs called the VB3 Microkeyer. There was a huge analog board that sat over the power supply, and a digital board that plugged into a slot. You removed about eight of the TTL chips from the Apple II logic board and replaced them with ribbon cables to the digital board, and there was a wider ribbon cable running from that board to the analog board. The college television studio had one, and I wrote software for it to perform various wipes. In addition to fixing the Apple II's video output to meet NTSC spec, it also added a new hires display mode that scanned memory in a completely linear order, instead of the usual interleaved fashion. This made writing software for wipes somewhat easier. Eric

I wrote about the Video Associate Labs VB-3 Microkeyer. Sellam replied: No idea. I doubt that very many were sold. The prices was in the low thousands of dollars. I was given one in exchange for giving the company some of the software I'd written for it. If you can find out what happened to all my computer stuff that was lost in a move in the mid-1980s, maybe you can find it. Eric

The reason people call color encoding on the Apple "artifacting" is because it was cleverly designed to take advantage of digital signals at the color burst frequency. That doesn't make the resulting waveform have any less "colorness" to it; the monitor is correctly interpreting it per the NTSC spec. For instance, people talk about how when you put a green pixel next to a purple pixel in an HGR mode, you get white as an "artifact". But that's because the NTSC signal that you get out for that pixel pair is essentially DC, so there is no color component. Naturally the monitor must interpret this as white. It's not the monitor being fooled, it's the naive programmer. The main part of the NTSC spec that the Apple II doens't meet is the relationship of color carrier timing to horizontal timing, which is supposed to be exactly 227.5:1, but on the Apple II was deliberately made 228:1 instead, so that the color carrier phase is the same on each line rather than alternating phase by 180 degress. The Apple has some other minor timing deviations, and the main oscillator usually isn't adjusted accurately to meet all the other specs (e.g., FCC spec on color carrier of +/- 10 Hz, wich is better than 3 PPM). But no other consumer gear normally meets that spec either. Anyhow, the color encoding on the Apple II works fine. That's not the problem. They looked exactly like they would on a normal Apple II. They just had correct timing. It rendered it as NTSC-compliant output. Eric

If you wanted color you either bought a PAL card, RGB card and monitor or Apple's not-quite-NTSC (which doesn't produce a color picture from other NTSC sources) color monitor. Even so running the RGB output of the IIgs through a scan doubler will give a better picture on a VGA CRT monitor than using the running the composite output through a TV card. I've read that scan doublers don't work well with some LCD monitors, in that case using the TV card maybe a better option.
