Personal Computer History: 1975-1984
Although Microsoft was an early participant in the fledgling PC market, personal computer history does not begin with IBM or Microsoft.
The MITS Altair 8800 was the first personal computer, debuted in 1975, and was followed by the IMSAI 8080, an Altair clone.
Both used the Intel 8080 CPU. (Yes, cloning has been around that long!)
In the same year, Zilog introduced the Z-80 CPU, and MOS Technology released the 6502.
Bill Gates and Paul Allen founded Micro-soft after writing a BASIC compiler for the Altair.
The Apple I, Apple's only "kit" computer (you had to add a keyboard, power supply, and enclosure to the built motherboard), was designed around the 6502 processor in 1976 by Apple's two Steves (Jobs and Wozniak).
Electric Pencil, the first word processor, and Adventure, the first text adventure for microcomputers, were both released in that year.

When Dan Bricklin and Bob Frankston released VisiCalc, the first computerized spreadsheet, in 1978, software took center stage.
This transformed the personal computer from a toy or a replacement for the electric typewriter into a practical business tool.
WordMaster, later renamed WordStar, was released, and for years it dominated the word processing business.
Atari used its video game skills and brand recognition to break into the personal computer industry, while Epson released the TX-80, the first low-cost dot matrix printer.
The database, the third key software category, debuted in 1979 with Vulcan, the ancestor of dBase II and its successors.
Hayes also created a 300 bps modem in same year, establishing telephony as a personal utility.

Texas Instruments' ill-fated TI-99/4A computer system was likewise released in 1979 as the personal computer industry's first 16-bit computer.
It was hampered by an 8-bit bus for memory and peripherals, which considerably hindered memory access.
With the $299 VIC-20, Commodore opened the floodgates of home computing in 1980. Sinclair tried to one-up them with a $199 kit computer, the ZX80, which was quite popular in Britain, but it was destined to remain a bit player in the PC
The Apple III, which came with 128 KB computer memory, an inbuilt floppy drive, and Apple II emulation, was yet another 1980 tragedy.
Unfortunately, it didn't work well, causing Apple to recall all of them, repair a number of issues, and rerelease the Apple III with 192 KB of RAM later.
The 5 MB Profile was also Apple's first computer to support a hard drive.
According to estimates, there were one million personal computers in the United States in 1980.
Adam Osborne introduced the first portable computer in early 1981.
The Osborne 1 was about the size of a suitcase, ran CP/M, had two 5.25′′ floppies, and a tiny 5′′ display.
The ingenious machine came with around $1,500-2,000 in software, and the entire package cost $1,899.
The Epson HX-20 was the first laptop computer to be released in 1981. (a.k.a. Geneva).
The HX-20 was around 8.5′′ by 11′′ and 1.5-2′′ thick, with a microcassette for data storage.
An LCD panel above the keyboard displayed four lines of 20 characters.
The IBM Personal Computer
Of course, the release of the IBM PC on August 12 was the most significant event in 1981 for the personal computing sector. This
