Sanyo MBC-555

The Sanyo MBC-555 developed the MBC-550 with dual floppy drives and bundled business software while retaining its inexpensive 8088 architecture and high-resolution colour display.

It became the better-known member of Sanyo’s early 16-bit desktop family and offered a complete office package at an aggressive price.

Notable Features

• Two built-in floppy drives
• Bundled business software
• High-resolution eight-colour display

Historical Significance

• It became the better-known member of Sanyo’s early 16-bit desktop family and offered a complete office package at an aggressive price.

Collector’s Notes

• Disk compatibility is unusual and original Sanyo system disks are important; inspect the proprietary keyboard and expansion cards.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
