Sord M223

The Sord M223 was an integrated Z80 business computer built around a 12-inch monochrome display and twin floppy storage. It combined Sord’s operating software with an S-100 expansion bus, allowing the system to adapt to accounting, scientific and office applications.

Several Mark revisions were marketed, including disk-based and hard-disk configurations. The Mark II and higher-end Mark VI illustrate how Sord developed one platform for a range of professional installations.

Notable Features

• Integrated 12-inch green monitor and dual 5.25-inch floppy drives.
• S-100 expansion bus supported additional controllers and specialist hardware.
• Later Mark configurations included hard-disk storage.

Historical Significance

• Continued Sord’s line of complete small-business systems rather than kit computers.
• Its expandable design supported the company’s growing PIPS and office-software ecosystem.

Collector’s Notes

• Mark numbers identify materially different factory configurations, so documentation should match the exact machine.
• The integrated CRT and aging disk hardware make careful transport and restoration important.
