Torch 725

The Torch 725 repackaged the company’s multi-processor Professional architecture as a more integrated single-module workstation. It supplied 1MB of RAM, a 20MB hard disk and two floppy drives with a high-resolution monitor and 102-key keyboard.

Customers could choose CPN for CP/M-compatible business programs or Unix for development and technical work. A 725T version added telecommunications functions to the standard network-capable model.

Notable Features

• Integrated 1MB of RAM, a 20MB hard disk and dual floppy drives.
• 102-key keyboard and high-resolution display presented a more conventional professional workstation.
• 725T variant added telecommunications capability.

Historical Significance

• Consolidated Torch’s earlier stackable Professional modules into a more practical complete system.
• Served organisations needing both established Z80 business software and a Motorola 68000 Unix environment.

Collector’s Notes

• Confirm whether a machine is the standard 725 or telecommunications-equipped 725T.
• Multiple processors and proprietary storage controllers make complete documentation valuable.
