Gary Kildall wrote CP/M. Tim Patterson, an engineer at Seattle Computer Products, wrote an operating system similar to CP/M called QDOS. QDOS was bought by Microsoft in 1981 and remade into MS-DOS. So Tim Patterson is the real maker of MS-DOS.
@LegoLoverFilms It's debatable when he based it on a CP/M manual he bought from Radioshack for a few dollars. Would you consider somebody copying someone else's test answers the original author of said answers?
Hell, QDOS was even short for Quick and Dirty Operating System.
That is true, but he only copied the design. He had to re-write the operating system, which takes a long time. Plus he had to write it in assembly, which is fairly complex.
@LegoLoverFilms A long time? Now you're probably thinking about an operating much more complex than DOS or CP/M because those were extremely basic operating systems. Those early operating systems could have been in about a week and QDOS did stand for Quick and Dirty Operating System.
Also, programming stuff in Assembly isn't THAT difficult, I've programmed some stuff in Assembly myself.
@LegoLoverFilms, don't you know that systems analysts are ranked above programmers - meaning those who design a system are smarter than those who code it.
QDOS was written to be a clone of CP/M so it could run popular CP/M business software, such as WordStar and dBase.
Kildall created the business and the market that Paterson and Gates then effectively stole.
@LAG09, less code doesn't mean easier code, esp. not when u had to write programs to control hardware. 3D games r much more complex today, but I'd like to see how long it takes you to come up with an efficient line drawing algorithm. If I gave u a year, I doubt u could come up with a decent routine to draw a straight line between two points on the screen. A mathematician came up with a solution - it's not hard to implement, but it took a very intelligent guy to come up with the solution.
i wouldn't go as far as to compare them to the third Reich, but there OS is expensive. oh and what that hell is that groaning sound? it sound like a zombie from half life 2
"Gary Kildall the real maker of MS-Dos"
No.

@LAG09 Yeah I've built operating systems in Assembly before, much similar to DOS. I didn't mean it took a long time, but it sure wasn't simple.
So sure, he copied the design. But not the code.

@LAG09 and of course I mean "an operating system," not "operating systems."
