![]() ![]() On mainframe computers and minicomputers, CAD was becoming a staple in design and engineering as early as the 1960s. CAD was a boon to architects who could master the keyboard and mouse as well as they had the pen and triangle. The later Apple Lisa and McIntosh, while having a great graphical user interface, also had a closed architecture that prevent porting over many popular applications.ĭevelopers who were working to move business applications from large expensive computers to the new microcomputers, including CAD (computer-aided design) programs, needed that open system and standards to be successful. Okay, Apple fans, the two Steves, Jobs and Wozniak, had the Apple II out first (1977) and it even had color graphics but the Z80 processor wasn’t up to handling the heavy lifting of many business applications, relegating their microcomputer to home use. The machine was based on open architecture and third-party peripherals, allowing developers to produce applications and devices galore. Arguably the trigger to releasing much of that creativity was the introduction of the IBM PC (personal computer) in 1981. The entrepreneurial spirit and creativity necessary to develop new and valuable software applications can be found around the world. Not all great software comes from Silicon Valley USA. ![]()
