Contrary to what its name may suggest, the Sanyo MPC-1, a.k.a Wavy1, was not the first MSX computer released by Sanyo. It looks very similar to the MPC-2, but has less RAM. This rare machine was available only in red and aimed at the Japanese market. The power supply is internal.

The MPC-1 is a MSX1 with a MSX-Engine T7775. The used VDP is the Toshiba T6950, which does not support some undocumented features of the Texas Instruments TMS9918, TMS9928 and TMS9929 VDP's.
