In 1829 Perth (Western Australia) was founded; in 1851 Isaac Singer was granted a patent for the sewing machine; in 1877 Edison made the 1st voice recording; in 1908 the first Model-T was build and in 2000 the Russian submarine Kursk sank killing 118 souls. In 1981 IBM released their first PC, the 5150, with 16kb of ram.

Do you remember your first PC?

IBM launched the model 5150 on the 12th of August 1981. You could buy one for US$1565 (about US$4500 in 2019 terms). It had a memory of between 16kb and 640kb (yes, less memory than one of those songs you're listening to through Spotify).


The release of the IBM personal computer wasn't supported by all employees at IBM, in fact one is quoted as saying "Why on earth would you care about the personal computer? It has nothing at all to do with office automation."


It was immediately successful with a report that 40,000 were ordered on the first day; a much higher demand than IBM had anticipated. The PC went on, in 1983, to surpass sales of the Apple II with 750,000 units being sold.

The model 5150 was eventually discontinued in 1987.
