Description

Computer

The PHC-70FD is a computer released on the Japanese market by Sanyo. While this computer is an all in one, the floppy disk drive is placed facing the user.

A Ren-Sha Turbo (autofire) is placed on the left of the disk drive. This model is not intended to add second floppy drive.

This computer is usually called Wavy70FD in Japan.

Note: Some exemplars have the reference PHC-70FDA on the label. The A corresponds probably to a revision to fix a hardware issue.

The PHC-70FD has been adapted for the Arabic countries - see Sakhr AX-370 - with more RAM and a MSX2 BIOS.
