Sord M23P

The Sord M23P repackaged the M23 business environment as a transportable computer. Its luggable cabinet contained twin 3.5-inch floppy drives and could use a compact LCD or an external colour monitor.

With 128KB of memory, Sord OS and CP/M support, the M23P brought familiar PIPS business applications to users who needed to move a complete workstation between offices or demonstrations.

Notable Features

• Portable version of the M23 architecture weighing about 9kg.
• Twin 3.5-inch floppy drives reduced the bulk of its storage system.
• Supported an 80x8 LCD or a full external CRT display.

Historical Significance

• An early attempt to make a complete Japanese business microcomputer transportable.
• Preserved M23 and PIPS software compatibility in a distinctive luggable format.

Collector’s Notes

• The optional LCD has far fewer text rows than the external display mode.
• Check the condition of the carrying hardware, display connections and uncommon 3.5-inch drives.
