16 February 1984 - IBM portable PC introduced

Digital Innovation Days

The introduction of the IBM Portable Personal Computer 5155 - a product whose roaring success surprised many, including IBM itself - on the 16th of February, 1984 popularised personal computers for everyday use. Weighing about 30 pounds, this computer had the following specifications: built-in ROM Basic, 256K memory standard, 9-inch 25x80 monochrome amber screen which could display graphics, DOS, and Intel 8088 4.77MHz CPU. The keyboard could be detached or folded and snapped shut in the case covering the computer. Priced at $2900, it was an immediate hit with the public and became the first personal computer to gain widespread adoption by the industry.

Initially, IBM could not find enough applications for this PC to justify acceptance on a broad basis. Moreover, even if this idea could be approved, it would not have been completed in a short timeframe. However, Bill Lowe, a lab director at IBM, stepped forward and claimed that he could develop a portable personal computer within a year. It was then that a team consisting of 12 developers was established which set out to create this device in 12 months. They were tasked with devising a plan for the software, hardware, marketing setup, and sales strategy. As the plan progressed, more talent and expertise was brought into this project.

Although personal computers were available as early as the 1970s, they provided very few applications that did not justify widespread and mainstream use. However, IBM offered a full suite of important applications that could justify broad adoption by the market. It became so popular that for a year or two, the Columbia Business School required every student to have this computer. In addition to this, it was IBM’s brand recognition as well as the massive marketing campaign that led to the fast growth of the personal computers industry. Furthermore, this computer was widely cloned and gave birth to a vast ecosystem of hardware, software, and peripherals to use with it.
