Description

Computer

The Sanyo MPC-2300 is the adaptation of the PHC-23J computer, also known as the Wavy 23, for the Soviet Union. It was not sold in shops and could only be used in some schools or administrations.

This computer has a Russian keyboard and a non-standard modem with switch (CALL COMINI does not work). It was mainly used by students in network with the MPC-2500FD.

The switch probably allows to initialise the serial port.

It is unsure to what refers the C8 part added on the label, maybe it means "Class 8" and would be similar to the system on the Yamaha YIS-503IIIR and Yamaha YIS-805/128R2 computers: in the Yamaha MSX-Network, up to 8 student machines are connected to a teacher machine using one of the floppy disk drives for centralised file storage.

Firmware

The firmware is a communication terminal software that can be launched from MSX-BASIC with CALL INIT or _INIT.
