Description
Computer
The Sanyo MPC-10mlII, a.k.a Wavy10mkII, is a more colored and slightly improved version of the MPC-10, the first MSX computer released by Sanyo. It has only one cartridge slot, but was sold with a lightpen, for which a hole is provided on top.
The machine has an integrated lightpen interface with firmware (Lightpen Graphics) and an expansion bus: it can be used as second cartridge slot with an adapter.
Size: 385(W)×62(H)×242(L)mm
Weight: 2.3kg
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-10mkII.
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.

Firmware
The built-in firmware is automatically launched when booting the computer. You access a menu with choice between MSX-BASIC and Lightpen Graphics, a drawing program written by HAL Laboratory.
This utility requires a lightpen and comes with a MSX-BASIC extension called Expander BASIC. It allows to save your drawings in a MSX-BASIC program, which uses the additional instructions.
You can also optionally write directly programs using these instructions. When you choose 'MSX-BASIC' in the main menu of this utility, the Expander BASIC is indeed available for using (even without lightpen).
