The SV-328 is an 8-bit home computer introduced by Spectravideo in June 1983. It was the business-targeted model of the Spectravideo range, sporting a rather crowded full-travel keyboard with numeric keypad. It had 80 kB RAM (64 kB available for software, remaining 16 kB video memory), a respectable amount for its time. Other than the keyboard and RAM, this machine was identical to its little brother, the SV-318.

The SV-328 is the design on which the MSX standard was based.[1] Spectravideo's MSX-compliant successor to the 328, the SV-728, looks almost identical, the only immediately noticeable differences being a larger cartridge slot in the central position (to fit MSX standard cartridges), lighter shaded keyboard and the MSX badging.

Reference to the operating system Microsoft Extended BASIC is not to be confused with MSX BASIC, although some marketing at the time claimed that Microsoft Extended is what MSX stood for.
