Thanks to Tomas Karlson, all relevant technical manuals and software on the Spectravideo SVI.318 and SVI.328. And some SVI.728 and other Spectravideo devices infi files also.
SVI.328
Technically speaken, the SVI.328 is not a MSX. But it is defnitely a member of the family with many similarities in hardware (VDP, slots, PSG) and software (Basic).
And, since it preceeded the MSX standard not very long and is largely identical, it shows that Spectravideo contributed a lot to the MSX standard from the SVI.328.
