Tandy 1000 EX

The Tandy 1000 EX placed a faster 7.16 MHz 8088, floppy drive and keyboard in one compact case. Side-mounted PLUS connectors provided expansion without a separate desktop system unit.

Its approachable all-in-one form and enhanced sound and graphics made the EX a popular first family PC.

Notable Features

• Processing is provided by Intel 8088-2 at 7.16 MHz.
• The standard memory configuration was 256KB standard; expandable to 640KB.
• Display hardware provided Tandy/PCjr-compatible sixteen-colour graphics.

Historical Significance

• Its approachable all-in-one form and enhanced sound and graphics made the EX a popular first family PC.
• 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.
