Apple released the Lisa computer in 1983 as one of the first desktop computers with a graphical user interface, or GUI. Although the Lisa was technologically great, commercially it was not a success. The high price point of $9,995 was so prohibitive that only about 10,000 Apple Lisa's were sold in the first two years.
Here are some of the technological advancements over other computers from the same era:
- Graphical User Interface
- Hard drive support
- 1MByte RAM, expandable to 2MB
- Protected Memory OS
There were some downsides to some of the technical implementations as well. The Lisa OS was complex, and the protected memory was implemented without a memory manager, making the CPU work overtime. This caused the Lisa GUI to feel sluggish and it had an impact on hard drive performance as well
The Apple Lisa was quickly followed by the Apple Macintosh, which, despite it's lesser technical qualifications, was a resounding commercial success.
