I think IBM introduced the PC in 1982, maybe 1981! By then Tandy
had the Model III out, but very limited software, Apple had the Apple
as a kit. The calculators of the early '70's, at least HP's was several
hundred dollars. Texas Instruments had the plain vanilla calculators--
-- add, subtract, etc. at that time for under $100. I also vaguely rem-
member an Oswald computer, with a tiny, tiny display. Compuserve
sold info by the page early '80's, and the page they chose as the standard
fit the tiny Osawal screen -- and that may be the wrong logo name, hi.
The entire idea first started at Farichild Semiconductor, but they
never got ahead of HP, TI, and later, IBM--- at least that is my
recollection of the chronology, which may be inaccurate.
