Tandy 1400 LT

The Tandy 1400 LT was an IBM-compatible folding laptop with a full-width LCD, two 3.5-inch floppy drives and a rechargeable battery. It brought Tandy’s DOS software and retail support to a more conventional portable design than the Model 600.

Successive 1400 FD and HD versions refined the same family with higher-density drives and hard-disc storage, so they are documented as revisions here.

Notable Features

• Processing is provided by Intel 8088 at 7.16 MHz.
• The standard memory configuration was 768KB including video memory.
• Display hardware provided CGA-compatible graphics on LCD or external monitor.

Historical Significance

• Successive 1400 FD and HD versions refined the same family with higher-density drives and hard-disc storage, so they are documented as revisions here.
• Storage-only and minor motherboard revisions are documented on this page rather than treated as separate products.

Collector’s Notes

• Confirm the catalogue number, processor, memory and drives because similar Tandy cases were sold in several configurations.
• Original DeskMate or system disks, keyboards, monitors and Radio Shack documentation add historical value.
