Talk:Number Nine Visual Technology

I'm not sure, but I think Number Nine began life in Chicago, IL, then later moved to Lexington, MA. Anyone know for sure?

The first reference corroborating the claim Number Nine made the first 256 and 16.7 million colour graphics cards is defunct. Vapourmile (talk) 22:50, 11 November 2019 (UTC)

Corrected for misunderstanding created by untypically modest documentation.
The Number #9 Revolution 512x32 is a 24bit graphics card with an 8bit overlay, RGB and sync output, compatibility with CCIR-624 PAL and RS-170A NTSC Genlocks and 5 bus-access modes. For its colour output in press-releases the manufacturer misleadingly claims a maximum 245,760 simultaneous on-screen colours. This figure emerges from the display resolution of 512x480 placing a literal upper limit binding the maximum number of unique displayable colours to the maximum 245,760 number of unique displayable pixels. In fact, the board has 1MB video RAM supporting an addressable graphics area of 512x512 pixels in 24bit RGB true colour with an 8bit overlay (3x8bit 512x512pixel primary-colour planes + 8bit overlay). It has 8bit and 16bit colour modes. It also supports the on-board NEC PD7220 16bit accelerated zoom, pan and window features. The documentation declares its combined 512x480 resolution and 24bit colour to be "capabilities previously unavailable on a microcomputer". http://www.vgamuseum.info/images/doc/no9/revolution_512_x_32_product_manual_version_2.00.pdf Vapourmile (talk) 15:51, 8 April 2021 (UTC)

Importance
Available since the early 1980s these represent some of the earliest cards available for microcomputers with their combination of colour-depth and resolution. The earliest cards of the series may have not have reached widespread public appeal but were if anything much too far ahead of the demand curve. Their mere existence alone at the time they appeared is sufficient to make them historically important. The Revolution 512x32 for example might be the first ever 24bit graphics card for a microcomputer and it is certainly among the first 24bit cards for the IBM PC and compatibles.
