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.
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, 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.
