The Sanyo MPC-6, a.k.a Wavy6, is same computer as the MPC-10, with more RAM, but the lightpen interface has been removed. The integrated light-pen holder is typically covered by a plastic cover plate with 64K written on it.

However, there's an expansion bus: it can be used as second cartridge slot with an adapter.

This computer was aimed at the Japanese market.

Sanyo released also the MPC-X, a Graphic Expander Unit which an extra VDP that adds 4 bitmap modes with 16, 4 or 2 colors on a palette of 512, high-resolution, superimposing, still function and zooming and uses lightpen. This expander needs to be connected to the MEB-01 slot expander, itself connected to the expansion bus of the MPC-6.

This computer was officially viewed as Videotex terminal when the Sanyo MPC-CAP1 Captain Unit was also bought and the contract was signed with the Captain company. It got then an additional label MPC-S1, meaning that it was good for this extra using.
