The original ADDS machine, the System 50,^[9] was intended to be used as a data entry system and not as a standalone computer. It has a form designer; data is entered into the form and sent via RS-232 to a mainframe. Since it has a microprocessor, Tandy matched it up with Peachtree Accounting software to market it as a business computer.

The system did not sell in large numbers. Radio Shack's next business system is 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.
