Tandy 3000

The Tandy 3000 was an IBM PC/AT-compatible business computer based on the 80286. Unlike the proprietary Tandy 2000, it used standard expansion graphics and ISA hardware to improve software and peripheral compatibility.

It marked Tandy’s business-line commitment to industry-standard PC architecture while the 1000 family retained enhanced home graphics and sound.

Notable Features

• Processing is provided by Intel 80286 at 8 MHz; later versions at 12 MHz.
• The standard memory configuration was 512KB or 640KB; expandable through AT slots.
• Display hardware provided MDA, CGA, EGA, VGA or Hercules according to installed card.

Historical Significance

• It marked Tandy’s business-line commitment to industry-standard PC architecture while the 1000 family retained enhanced home graphics and sound.
• 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.
