The CCG MSX Adapter For SVI-328 is a cartridge that you can insert in the cartridge slot of the non-MSX Spectravideo SVI-318 and SVI-328 computers.

It contains two 16kB EPROMs whose content correspond to a modified version of the BIOS/BASIC rom of the SVI-728, the first real MSX computer released by Spectravideo.

It will partially transform the SVI-318/328 into a MSX1 computer as it allows to

  • use MSX1 tape games
  • use MSX-DOS 1 (only on SVI-328 when a disk drive is connected)
  • switch from SVI to MSX mode without losing memory
  • load a MSX-BASIC cassette, switch to SVI mode and save in that mode

The documentation includes a list of the compatible MSX1 games.

It was manufactured in 1987 by the Spanish CCG company.
