The PHC-30 looks like the merger between the Sanyo MPC-5 and a data recorder. However, unlike the MPC-5, it has a printer port.

Additionally, this computer has an expansion bus slot, which can be used as a third cartridge slot with an adapter.

This computer was aimed at the Japanese market. It was sold with a demo tape.

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 PHC-30.

This computer was NOT officially viewed as Videotex terminal when the Sanyo MPC-CAP1 Captain Unit was also bought. Probably the reason is the RAM size limited to 16kB.

The PHC-30 is a MSX1 with a Z80A from Sharp (LH0080A). A volume control of the internal speaker is located on the right side.

Some sources say that this MSX1 has 32kB of RAM by mistake, probably because the manufacturer announced 32kB of memory (16kB RAM + 16kB VRAM).

Early models had a 13W internal PSU, while later models are 10W.
