Merged: Any Point, Any Color[edit]

I think that having Any Point, Any Color separate is fragmenting things a bit much now that we have a separate article for software-driven modes (they were moved from Atari 8-bit family because that article was *way* too long and the non-core information had to be moved out). The info on the subject here is almost as detailed as the article itself anyway. Any thoughts? Fourohfour 16:23, 22 April 2007 (UTC)

On second thoughts, I have gone ahead and merged the articles. No moves were involved, so this is reversible. However, I feel that this is the better setup for the reasons given above. Fourohfour 17:11, 22 April 2007 (UTC)

Creator, please verify[edit]

One thing; who *exactly* created Any Point, Any Color? Tom Tanida or Jeff D. Potter? The merged material and the stuff that was here seems to contradict itself. Fourohfour 17:11, 22 April 2007 (UTC)

There's no contradiction -- Tom Tanida created APAC, Jeff D. Potter used it to create the APACView application. jhf (talk) 09:19, 28 December 2008 (UTC)

80 column driver[edit]

I am not sute the best place to put this. My name is Simon Trew and I wrote an 80 column driver for the atari 8 bit using a 4x8 font and graphics mode 8. It was extremely quick compared to other similar drivers also you could substitute it for E: it had full integration into the OS so you could use it as your editor. The stupidest thing is that i did scrolling using memory moves whereas i should have just scrolled the display list, that slows scrolling a lot. You would think it would be out there on the net but I have never found it. If anyone finds it, get in touch with me I can give you a lot of info about it (and you might like it!). It was never published in a magazine cos it was kinda the time they were all closing down, I released it PD. SimonTrew (talk) 12:07, 10 June 2009 (UTC)

I also wrote The Pig Demo and the Cube Demo doing some rather odd display list tricks. As their names suggest they were not meant as anything other than demos of what you could do with the Atari graphics chips, though quite funny. I think these are available on the net.

Recalling more thoroughly, the 80 column mode also supported LOCATE by comparing the character on screen with those in the character set. This was pretty necessary as part of the input routine! It would (properly) fail if graphics had been drawn through the characters, and also if two characters were identical (or one the inverse of the other) then only the first, numerically, would ever be returned. Quite clever really, but slow (though individual character comparison did exit as soon as a character match was not found). Si Trew (talk) 07:29, 8 December 2009 (UTC)

Emulators and Any Points, Any Color (APAC)[edit]

Are there any emulators for Windows that fully support APAC modes? 173.58.64.64 (talk)

To the best that I know, all the popular emulators for Windows (atari800win, Atari800, Atari++, Altirra) do APAC mode reasonably well. —Preceding unsigned comment added by 71.236.47.253 (talk) 03:18, 23 December 2010 (UTC)
