Texas Instruments Portable Professional Computer

The Portable Professional Computer was a transportable version of the TI Professional Computer with an integrated monochrome CRT, detachable keyboard and internal floppy or hard-disk storage.

It carried TI’s proprietary professional architecture into the luggable market but faced strong competition from machines offering closer IBM PC compatibility.

Notable Features

• Transportable version of the TI Professional Computer
• Integrated display and detachable keyboard
• Shared operating-system and expansion environment with the desktop TIPC

Historical Significance

• It carried TI’s proprietary professional architecture into the luggable market but faced strong competition from machines offering closer IBM PC compatibility.

Collector’s Notes

• Its large enclosure, CRT and proprietary cards make complete working examples uncommon; verify the installed drive and display configuration.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
