What was the 1st personal computer?
Altair
A small firm named MITS made the first personal computer, the Altair. This computer, which used Intel Corporation’s 8080 microprocessor, was developed in 1974.
What were the 1st computers?
The first substantial computer was the giant ENIAC machine by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC was also the first machine to use more than 2,000 vacuum tubes, using nearly 18,000 vacuum tubes.

Where was the first personal computer made?
the University of Pennsylvania
Started in 1943, the ENIAC computing system was built by John Mauchly and J. Presper Eckert at the Moore School of Electrical Engineering of the University of Pennsylvania. Because of its electronic, as opposed to electromechanical, technology, it is over 1,000 times faster than any previous computer.
Which was the first personal computer sold to the public?
Kenbak-1
The Kenbak-1, released in early 1971, is considered by the Computer History Museum to be the world’s first personal computer. It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971.
Who invented first personal computer?
The Kenbak-1, released in early 1971, is considered by the Computer History Museum to be the world’s first personal computer. It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971.
Was the Macintosh the first personal computer?
The first Macintosh was introduced on January 24, 1984, by Steve Jobs and it was the first commercially successful personal computer to feature two known, but still unpopular features—the mouse and the graphical user interface, rather than the command-line interface of its predecessors.
What is the history of the personal computer?
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s.
What was the first computer in 1975?
The first personal computers, introduced in 1975, came as kits: The MITS Altair 8800, followed by the IMSAI 8080, an Altair clone. (Yes, cloning has been around that long!) Both used the Intel 8080 CPU.
What was the 1977 trinity of personal computing?
In 1977, three new pre-assembled small computers hit the markets which Byte would refer to as the “1977 Trinity” of personal computing. The Apple II and the PET 2001 were advertised as personal computers, while the TRS-80 was described as a microcomputer used for household tasks including ” personal financial management”.
What is the most important invention that led to the PC?
But one of the most significant of the inventions that paved the way for the PC revolution was the microprocessor. Before microprocessors were invented, computers needed a separate integrated-circuit chip for each one of their functions. (This was one reason the machines were still so large.)
