Which was the first computer launched by IBM?
Answers:
It really depends how you define "computer". The first IBM mainframe computer is the IBM 701 while the first IBM "personal computer" is the IBM 5100. There was also a Mark I in 1944... but is regarded more as a "Automatic Sequence Controlled Calculator".
IBM 701.
IBM made a number of key technological changes in the decade of the 1950s. In 1952, the company introduced the IBM 701, its first large computer based on the vacuum tube. The tubes were quicker, smaller and more easily replaced than the electromechanical switches in the Mark I (1944).
The 5100 Portable Computer.
The 5100 Portable Computer was announced by the IBM's General Systems Division (GSD) in September 1975. The Portable Computer was intended to put computer capabilities at the fingertips of engineers, analysts, statisticians and other problem-solvers. Available in 12 models providing 16K, 32K, 48K or 64K positions of main storage, the 5100 sold for between $8,975 and $19,975. The 5100 was available with either APL or BASIC — or both — programming languages.
But the first "recognized" personal computer from IBM.
In July of 1980, IBM representatives met for the first time with Microsoft's Bill Gates to talk about writing an operating system for IBM's new hush-hush "personal" computer. IBM had been observing the growing personal computer market for some time. They had already made one dismal attempt to crack the market with their IBM 5100. At one point, IBM considered buying the fledgling game company Atari to commandeer Atari's early line of personal computers. However, IBM decided to stick with making their own personal computer line and developed a brand new operating system to go with. The secret plans were referred to as "Project Chess". The code name for the new computer was "Acorn". Twelve engineers, led by William C. Lowe, assembled in Boca Raton, Florida, to design and build the "Acorn". On August 12, 1981, IBM released their new computer, re-named the IBM PC. The "PC" stood for "personal computer" making IBM responsible for popularizing the term "PC".
The first IBM PC ran on a 4.77 MHz Intel 8088 microprocessor. The PC came equipped with 16 kilobytes of memory, expandable to 256k. The PC came with one or two 160k floppy disk drives and an optional color monitor. The price tag started at $1,565, which would be nearly $4,000 today.
It was IBM model number 5150, and was introduced on August 12, 1981.
IBM 5150
Well you there isn't much information on IBMs first computer. IBM was formed in 1888, and one of it's first mass creations was punch cards(created in 1725), which were used to give instructions to computers. IBM then changed from software to hardware/weaponry in the 1940s. I would have to say the Harvard Mark I built for the Navy in WWII was the first IBM computer. SAGE* was the second computer. They also created the first 64 bit super computer in 1961.
