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 used in network with the MPC-2500FD.

The switch probably allows to enable/disable the modem. It is unknown to what refers the C8 part added on the label.
