Rumors spread in late 1983 of a new computer in 1984 called the "Commodore 444" or "Ted", with built-in word processing and spreadsheet software, and that it would be one of four new computers that would replace the VIC-20 and C64, which the company would discontinue. The company's third salvo which, as it turned out, was fired just as most of Commodore's competition was leaving the home computer market was the C116, C16, and 264, which became the Plus/4. There were also prototypes of a 232, basically a version of the Plus/4 without the software ROMs, and a V364 which had a numeric keypad and built-in voice synthesis. The latter two models never made it to production. All these computers used a 6502 compatible MOS 7501 or 8501 that was clocked approximately 75% faster than the CPUs used in the VIC-20 and C64, and a MOS Technology TED all-in-one video, sound, and I/O chip. The Plus/4's design is thus philosophically closer to that of the VIC-20 than that of the C64.
