We used this equipment to provide business management, accounting and computer systems integration consulting services to others from 1980-87 using Tandy software (word processing, spreadsheet, database, accounting, etc. modified by us as needed as well as custom software written in Basic and Cobol. In late 1983 we acquired a Tandy 2000, an extremely fast  MS-DOS machine with the coolest graphics capabilities, but ultimately was "software-orphaned" because of its processor (see the Wikipedia entry). Ultimately, we reluctantly accepted the MS-DOS/80286 future, although the equipment above did everything that we do today but graphics and without the convenience of cut-and-paste. The improvement over a typewriter, a calculator, and written ledgers and records cannot be overstated. We also were "on line" sort of, using Compuserve.
