January 19th

On this day - January 19th 1983 - The Apple Lisa was released

The Apple Lisa was one of the first computers with an graphical user interface aimed at individual business owners. Steve Jobs was part of the development process that started 1978, however in 1982 he was forced out of the project.  The operating system taxed the processor (5 MHz) so heavily that it felt sluggish especially scrolling trough documents. NASA was the biggest customer and used it for project management. When Apple finally discontinued the Lisa in 1986, it caused NASA a lot of problems since they were using a no longer supported platform. In 1989 Apple disposed of 2,700 unsold units in a landfill to receive a tax write-off. The Lisa project was a commercial failure that ended up selling 100,000 units. The biggest disadvantage was the price point 9995$ (23,700$ 2016$). The competing computers from IBM dominated the sales numbers due to the lower price.
