A dedicated game machine that succeeded in keeping the price down by cutting out the keyboard from the "game PC" SC-3000.
The CPU was 8 bits, about the same as that of the MSX PC of the time.
Games could be played on the dedicated cartridges released by SEGA, as well as on the original Tsukuda Othello Multivision cartridges.
