A NeWS server "can run as an application on a single process personal computer or bitmapped terminal, communicating with clients on some multi-process system via a phone line or network". NeWs has been written with portability in mind. Sun has shown a version of NeWS running on the Atari ST over 1200 baud phone lines. And note that the Atari does not even support multiprocessing. NeWS implements its own lightweight type of processes. Porting NeWS to the Amiga should be fairly easy, though a source licence will cost $25,000 to a private company, and $1000 to a University.

It is a complete processor and some products are already available that use it: the Number Nine Clipper graphics board for the IBM PC (which also includes the Intel chip, see later) and the new board from Tektronix (also for the PC) that runs Grafpoint Tgraf-05 and Tgraf-07 (tek 4105 and 4107 graphics emulators). > There are a number of other blit chips or video/processor chips > incorporating "blit" functions.

Among other, Intel has the 82786 graphics processor that includes a bit blitter, and National has the AGCS (Advanced Graphics Chip Set) which also includes a blitter. To give you an idea of the prices, the less sophisticated Intel 82876 costs about $150, the TI 34010 costs about $500, and the National chips set is not completely available yet. -- Marco -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Marco Papa 3175 S.
