The Tandy 1000, introduced by Tandy Corporation (Radio Shack) in November 1984, was a significant vintage computer recognized for its affordability, compatibility, and innovative features that appealed to home and educational markets.

Technical Specifications:

  • CPU: Intel 8088 processor at 4.77 MHz (original model); later models offered higher speeds and processors including 8086, 80286, and eventually 80386SX.
  • Memory: Initially shipped with 128 KB RAM, expandable up to 640 KB through ISA expansion cards.
  • Storage: Standard configuration included a single 5.25″ floppy disk drive (360 KB capacity). Additional floppy drives or hard drives (such as the 10 MB drive in the Tandy 1000HD) were optional upgrades.
  • Graphics: Enhanced CGA-compatible graphics (“Tandy Graphics Adapter”), capable of displaying up to 16 colors simultaneously—a significant improvement over standard CGA’s four colors.
  • Sound: Integrated Texas Instruments SN76496 or NCR 8496 Programmable Sound Generator (PSG), providing three-voice sound superior to standard IBM PC audio at the time.
  • Ports and Expansion: Built-in joystick ports compatible with TRS-80 Color Computer peripherals, parallel printer port, and ISA slots for additional expansions. Later models featured integrated peripherals directly on the motherboard.
