Type | Home computer |
Developer | Spectravideo |

Processor | Zilog Z80A @ 3.6 MHz |
Memory | 64 KB (+16 KB VRAM) |
Operating system | Microsoft Extended BASIC CP/M |
The SV-328 was the business-targeted model of the Spectravideo range, sporting a rather crowded full-travel keyboard with numeric keypad, and no built-in joystick (though the arrow keys mimicked this function). 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 the SV-318.
The SV-328 is the design on which the MSX standard was based. Spectravideo's MSX-compliant successor to the 328, the SVI-728, looks almost identical, the only immediately noticeable differences being a larger cartridge slot (to fit MSX standard cartridges) and the MSX badging.
