Millipede Electronics - Prisma 3

The Millipede Prisma 3 Graphics system was almost the ultimate TV graphics add on for use, originally with the BBC B and later, for A300 / A400 / Risc PC series computers running RISC OS 3. The system is an 8 bit RGB 768 pixel x 574 lines interlaced display which is fully broadcast genlockable. It is supplied as an external mains powered system box, with a podule control card connected by 50 way ribbon cable. The system had a 64 bit internal graphics bus for high speed graphics processing and a Hitachi HD63484P98 9.8MHz Advanced CRFT controller. It has 6 MB RAM which could be used to provide up to 14 frames worth of animation.

This unit was bought by CHris Whytehead from Paul Middleton of Uniqueway who said that the system was one of a number used to provide graphics for the 1992 General Election coverage on BBC Wales / S4C.
