NeXTstep object oriented software
NeXT was founded in 1985 by Apple co-founder Steve Jobs. Sales of the NeXT computers were relatively limited, with estimates of about 50,000 units shipped in total. Nevertheless, its innovative object-oriented Nextstep operating system and development environment were highly influential. It had a 25MHz CPU, 330 or 660 MB hard drive, and up to 4 MB of RAM. The original price of $6,500 equals $12,000 in 2011 dollars, using the consumer price index.
