About August 12

August 12 is the 224th day of the year in the Gregorian calendar (225th in a leap year). There are 141 days remaining until the end of the year.

The significance of August 12

On August 12, 1981, IBM released the Model 5150 Personal Computer at a press conference in New York. Priced at $1,565, it ran MS-DOS on an Intel 8088 processor and came with 64 KB of RAM. IBM’s decision to use off-the-shelf parts and publish an open architecture meant that within two years clone manufacturers like Compaq were producing compatible machines. That single decision shaped the entire structure of the computing industry. In 1960, NASA launched Echo 1A, a silver balloon 100 feet across that orbited Earth and reflected radio signals — the first communications satellite. The UN has observed International Youth Day on August 12 since 2000.
