| 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. |
