About: NeXTdimension

An Entity of Type: organisation, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

NeXTdimension (ND) was an accelerated 32-bit color board manufactured and sold by NeXT from 1991 that gave the NeXTcube color capabilities with PostScript planned. The (NuBus-like) card was a full size card for the NeXTcube, filling one of four slots, another one being filled with the main board itself. The NeXTdimension featured S-Video input and output, RGB output, an Intel i860 64-bit RISC processor at 33 MHz for Postscript acceleration, 8 MB main memory (expandable to 64 MB via eight 72-pin SIMM slots) and 4 MB VRAM for a resolution of 1120x832 at 24-bit color plus 8-bit alpha channel. An onboard C-Cube CL550 chip for MJPEG video compression was announced, but never shipped. A handful of engineering prototypes for the MJPEG daughterboard exist, but none actually function.

dbo:abstract
  • NeXTdimension (AR) est une carte accélératrice 32 bits fabriquée et vendue par NeXT de 1990 qui a apporté le rendu couleur au NeXTcube en PostScript. La carte utilise un des quatre ports Nubus disponible, et avait des dimensions physiques importantes.Les caractéristiques de la NeXTdimension sont : * S-Vidéo en entrée et sortie * sorties RGB * Un microprocesseur Intel i860 RISC 64 bits entrainé à 33 MHz pour l'accélération Postscript * 8 à 32 Mo de mémoire RAM et 4 Mo de VRAM pour permettre une résolution 1120 * 832 en couleurs 24 bits et canal alpha 8 bits. Une carte fille C-Cube CL550 avec compression MJPEG matérielle avait été annoncée, mais n'a jamais été vendue.Une poignée de prototypes pour cette carte existent, mais aucune n'est fonctionnelle. Le noyau Mach a été utilisé comme système d'exploitation pour la carte. Grâce au microprocesseur 32 bits PostScript sur la NeXTdimension, elle rend le traitement des niveaux de gris plus rapide par rapport à une NeXTCube non équipé d'une NeXTDimension. Le prix officiel pour un NeXTdimension vendu comme extension pour un NeXTcube est de 3995 dollars américains. (fr)

An onboard C-Cube CL550 chip for MJPEG video compression was announced, but never shipped. A handful of engineering prototypes for the MJPEG daughterboard exist, but none actually function. A stripped down Mach kernel was used as the operating system for the card. Due to the supporting processor, 32-bit color on the NeXTdimension was faster than 2-bit greyscale Display PostScript on the NeXTcube. Display PostScript never actually ran on the board so the Intel i860 never did much more than move blocks of color data around. The Motorola 68040 did the crunching and the board, while fast for its time, never lived up to the hype. Since the main board always included the greyscale video logic, each NeXTdimension allowed the simultaneous use of an additional monitor. List price for a NeXTdimension sold as an add-on to the NeXTcube was US$3,995 (equivalent to $7,950 in 2021), and US$2,995 (equivalent to $5,960 in 2021) for the MegaPixel Color Display. (en)
