The SVI-728 is the first home computer from Spectravideo that complied fully with the MSX home computer specification.[1][2] It was introduced in 1984.[3] The design is virtually identical to that of the earlier SV-328, which did not comply fully with the MSX standard.

The SVI-738 is a portable version of this computer.
