DOS also included a BASIC language interpreter, which was a standard feature in all personal computers of the era.
As a result, the PC-DOS 1.0 command line was pretty anemic, only including a few commands to set the date and time, manage files, control the terminal, and format floppy disks. Running in memory up to 640 kilobytes, DOS really couldn't do much more than manage the hardware and allow the user to launch applications.

HISTORY OF DOS PC
In turn, Microsoft acquired 86-DOS from Seattle Computer Products, applied various updates, and debuted the new version with the IBM PC as IBM PC-DOS. One of those was the operating system, licensed from Microsoft. After a rapid development cycle, IBM released the IBM 5150 Personal Computer (the original "IBM PC") in August 1981.Ĭreating a computer from scratch is no easy task, so IBM famously used "off-the-shelf" hardware to build the PC, and licensed other components from outside developers. The personal computer became such a hot topic that IBM decided to enter the market. The earliest personal computers I remember seeing included the Commodore, TRS-80, and Apple. You could finally have a computer in your home-the "personal computer" had arrived! But the advent of the microprocessor brought about a computing revolution in the 1970s. The Tao of Programming, Geoffrey James, InfoBooks, 1987Ĭomputing used to be limited only to expensive mainframes and "Big Iron" computer systems like the PDP11. The master coughed and shifted his position slightly. "And is the Tao in the DOS for a personal computer?" "It is even in a video game," said the master. "Is the Tao in a video game?" continued the novice. "Is Tao in a hand-held calculator?" asked the novice.
"The Tao is embodied in all software-regardless of how insignificant," said the master.
