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 (to fit MSX standard cartridges) and the MSX badging.
