Sanyo PHC-25

The Sanyo PHC-25 was a compact home computer with Microsoft BASIC, colour graphics and cassette storage in a low-profile keyboard console.

It was part of Sanyo’s proprietary home-computer range immediately before the company adopted MSX.

Notable Features

• Programmable colour graphics
• Microsoft BASIC in ROM

Historical Significance

• It was part of Sanyo’s proprietary home-computer range immediately before the company adopted MSX.

Collector’s Notes

• Regional video and keyboard versions differ, and software is less common than for Sanyo’s later MSX machines.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
