Description
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.
