Do you still have it? Either way, would you grant a licence on the material so that we could use it in this article? I can probably find it. Note that the three SMMU pics there I think I took in the first place, but I found them on a page which had mirrored some of your old page. I remember there were two tiers of shots, those from before and those from after you implemented background dithering. I'm building a win95 box in order to actually run SMMU/DOS and take some proper shots :-) -- [[User:Jdowland|Jdowland]] 21:31, 20 Jun 2005 (UTC) I've lost the original page and images I had, unfortunately. The system works by using the extended ASCII text mode "gradient" characters (there are ~4-5 of them). When the palette is set, the hue and brightness of each colour is calculated from the palette entries. The hue is then used to select the text-mode colour to use for the character, while the brightness is used to select the character to use. The extended mode ascii characters used are (descriptions I ''think'' are correct): * "space" character (32): all background * 0xb0: 20% foreground * 0xb1: 40% foreground * 0xb2: 60% foreground * 0xdb: 80% foreground The original version of the SMMU textmode renderer used black as the background, and the selected colour as the foreground (ie, 5 steps). I later improved on it by adding greater colour depth and using the background colour. Basically text mode has two sets of colours; the second are the same as the first but brighter (1 is blue, 9 is "bright blue"). So instead of going from black -> colour, I made it go black -> colour -> bright colour (the first stage having black background + colour foreground, the second stage having colour background + bright colour foreground). This effectively doubles the colour depth.
