Tandy 10 Business Computer System
short-lived product

The Tandy 10 Business Computer System is a product developed by Radio Shack in the late 1970s as a business-oriented complement to its 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 is 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. Features include:
8080 CPU
48K memory
80 x 24 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. 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.
This brief starts where responsible research should: with the source description of “Tandy 10 Business Computer System” as short-lived product. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as short-lived product. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 6, 2026. The linked authority identifier is Q7682523. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1978, 1979 and 1980.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
