This portable computer released by Tandy was a machine
designed for consumers who use regular PC but want to take smaller one
on the go. It was sold for 999USD and had a backlit LCD with nice
contrast, MS-DOS and Tandy DeskMate shell in ROM. Using other programs
required floppy disks. Battery allowed to work for about 3.5h without
charging. Tandy developed this notebook as an office machine - LCD is
clear, has large characters and has light. Inside, a Tandy DeskMate
operating environment has been included. Unfortunately there was a
problem when copying and pasting text between programs. DeskMate itself
hasn't gained big popularity but some companies released their software
with DeskMate support (e.g. Quicken).
Some companies sold external hard disk drives for Tandy, but they were slow as they used parallel port.
