The Tandy 10 Business Computer System was a short-lived product developed by Radio Shack in the late 1970s as a business-oriented complement to their TRS-80 Model I desktop computer. Released in 1978, the Tandy 10 was built for Radio Shack by Applied Digital Data Systems (ADDS), and was only sold by Radio Shack's dedicated computer center stores.[1]

The computer itself was about the size of a two-drawer filing cabinet, with a monitor and keyboard built into a desk-shaped console, along with two 8-inch floppy drives vertically mounted in the pedestal. Its features included:

  • 8080 CPU
  • 48K memory
  • 24x80 video display
  • Two dual-sided 8" diskette drives
  • Dartmouth BASIC
  • ADOS Disk Operating System

Optional:

  • Fortran IV language
  • Assembly Language program language

The original ADDS machine, the System 50,[8] was intended to be used as a data entry system and not as a standalone computer. The original "language" it contained was actually a form designer; data was then entered into the form and then "sent" via RS-232 to a mainframe. Since it had a microprocessor, Tandy matched it up with Peachtree Accounting software in an attempt to market it as a business computer.

The system did not sell in large numbers. Radio Shack's next business system was an extension of the TRS-80 product line, the TRS-80 Model II, released in May 1979. The Tandy 10 was discontinued in late 1980.
