The Thomson EF936x series is a type of Graphic Display Processor (GDP) by Thomson-EFCIS.[1] The chip could draw at 1 million pixels per second, which was relatively advanced for the time of its release (1982 or earlier). There are various versions of the chip with slightly different capabilities.[2]
The first version, EF9364 CRT Processor, was introduced in 1981.[3]
In 1982 Commodore released a "High Resolution Graphics" board for the PET based on the EF9365 and EF9366 chips, allowing it to display 512 × 512 or 512 × 256 resolution graphics.[4][5][6] The EF9366 was also used on the SMP-E353 graphic card for the Siemens SICOMP computer series and on the NDR-Klein-Computer introduced in 1984.[7]
Version EF9369, introduced in 1984, was used on computers such as the Thomson MO5NR[8], MO6[9], TO8,[10] TO9[11] and TO9+,[12] and from 1985 to 1989 on the DAI Personal Computer.
