Short History of OS/2, A

In the Beginning DOS - 1981 In 1981 when the original IBM Personal Computer was announced, IBM released three operating systems for it. How many of you remember that? Since I wrote the first IBM course on how to fix this original PC, I had to know at least a little about all three of them. IBM decided early in the development process of the PC that they did not want to hire a bunch of programmers to write software for it - especially an operating system. IBM wanted the hardware business and did not care about the software. Since there was no clear-cut contender for an operating system at the time, IBM approached three organizations about writing one for the PC.
