The Commodore Plus/4 was the most popular model of the Commodore 264 series which also included the Commodore 16 and 116 models all released in 1986. The onboard MOS Technology 7360 Text Editing Device (
TED) is an all purpose interface integrated circuit handling input, video and audio. This was a move backwards for Commodore in computer architecture as the
C64 celebrated the separation of audio capabilities into it's own chip. While the TED chip offered the same resolution as the VIC-II and almost 8x as many colors, it does not support sprites.
