__NOTOC__ History Development The IBM 5100 of 1975 was the first minicomputer made by IBM. APL models of the 5100 could essentially emulate a IBM System 360 mainframe.IBM 5100 computer https://oldcomputers.net/ibm5100.html oldcomputers.net 27 November 2020 The accelerate development the IBM PC was developed in the span of 12 months by extensively using components made by other companies.IBM Archives: The birth of the IBM PC https://www.ibm.com/ibm/history/exhibits/pc25/pc25_birth.html www.ibm.com 27 November 2020 23 January 2003 Launch A press release by IBM in late August 1981 touts the capabilities of the IBM 5150, including a brief mention that the system can be used to easily play video games. The IBM 5150 was released in September of 1981 at a base cost of around $1,565, a home use setup costing around $3005, and a business system costing around $4,500.IBM Archives: Announcement press release https://www.ibm.com/ibm/history/exhibits/pc25/pc25_press.html www.ibm.com 27 November 2020 23 January 2003 Because the only thing IBM actually made for the IBM PC was the BIOS, clones of the system existed within a year, though were quickly stopped by legal action.Send in the Clones - CHM Revolution https://www.computerhistory.org/revolution/personal-computers/17/302 www.computerhistory.org 27 November 2020 Compaq made a clone with a legally engineered compatible BIOS, paving the way for other clones to create the modern PC platform.Tales from 80s Tech: How Compaq’s Clone Computers Skirted IBM’s IP and Gave Rise to EISA - News https://www.allaboutcircuits.com/news/how-compaqs-clone-computers-skirted-ibms-patents-and-gave-rise-to-eisa/ www.allaboutcircuits.com 27 November 2020 enThe IBM Compatible or Clone - History of the Progression of Computer Technology - Electronic Tutorials and Circuits https://www.hobbyprojects.com/progression-of-computer-technology/the-ibm-compatible-or-clone.html www.hobbyprojects.com 27 November 2020 Technology There are many iterations of the IBM Personal Computer.

As mentioned earlier, once that was reverse engineered using clean room techniques, many legal clone machines were brought to the market.Send in the Clones - CHM Revolution https://www.computerhistory.org/revolution/personal-computers/17/302 www.computerhistory.org 1 March 2021 These clones were often cheaper or sported features the official IBM PC models lacked.Haigh Thomas The IBM PC: From Beige Box to Industry Standard cacm.acm.org https://cacm.acm.org/magazines/2012/1/144800-the-ibm-pc/fulltext 1 March 2021 en Gallery IBM 5150 Related IBM Computers Compaq Portable Ad-Lib sound output File:PEHMOPOP.ogg - An example music file similar to what would run on real Ad-Lib hardware.
