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.
