Sanyo MBC-550

The Sanyo MBC-550 was a low-cost 16-bit desktop with an Intel 8088, high-resolution colour graphics and MS-DOS. Its architecture resembled the IBM PC but was not completely hardware compatible.

An unusually affordable entry into 16-bit business computing, it attracted users through strong graphics and value despite compatibility limitations.

Notable Features

• High-resolution colour graphics
• Low launch price for an 8088 system
• MS-DOS with partial rather than full IBM compatibility

Historical Significance

• An unusually affordable entry into 16-bit business computing, it attracted users through strong graphics and value despite compatibility limitations.

Collector’s Notes

• Its disk format, keyboard and expansion hardware are distinctive; original boot disks are especially valuable.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
