MS-DOS Paternity Dispute Goes to Court
theodp writes "Might be more interesting as a Who's-My-Baby's-Daddy? segment on Maury, but a Court has been asked to decide the parentage of MS-DOS. Tim Paterson, whose operating system 86-DOS (aka QDOS) was sold to Microsoft in 1980, is suing author Harold Evans and Time Warner for defamation. In his book They Made America, Evans devoted a chapter to the late, great Gary Kildall, founder of Digital Research, describing Paterson's software as a 'rip-off' and 'a slapdash clone' of Kildall's CP/M."
...I thought it wasn't defamation if it was true.
Don't think of it as a flame---it's more like an argument that does 3d6 fire damage
If it comes out that this guy didn't have the right to sell Dos to them, then all Microsoft's subsequent OS's could see some additional legal issues coming up.
"A truly wise man realizes he knows nothing."
The book / film is about American inventors / innovators / corporate moguls for the last 200 years. Microsoft is in there because, like it or not, their OS has been the predominate one over the last 20 years. The book also discuss things like the steam engine and modern banking. Stop being an ass and find something useful to complain about, like how the book claim this guy's work underlies "every computer application today".

Funny, I heard that Unix is a 'rip-off' and 'a slapdash clone' of Multics. Is that true?
I've never heard anyone claim that Paterson lifted any code from CP/M, just that he wrote a clone of CP/M, instead of designing his own operating system. It was obvious that much of the design of QDOS was done by reading the documentation for CP/M. There's nothing illegal about that. Many people did the same thing to UNIX.

CP/M didn't keep track of the exact size of a file, just the number of 128-byte blocks allocated to it. This was OK for text files. You knew when you got to the end because you'd read a Ctrl-Z. But binary files could have Control-Zs in them anywhere, so all programs that read/wrote binary files had to store actual size - what should have been metadata - either as a header or in a separate file. Very un-Unix-like. But then, CP/M was a ripoff of RT-11, DEC's LSI-11 starter OS.

I would. For the continued royalties you could glean off it alone. Secondly, in it's day, it was the best Operating system around for a PC, hands down. DOS brought device handling up front, to the user. It was a major step in the direction that all OS' follow now. Without that history, much of the device layer we are accustomed to today, wouldn't be there. I was a professional in the field then and it's creation opened so many doors. It was a cool time to be paid to work with the stuff.
It was, just what it claimed to be a disk operating system. It was very simple, very low impact. This was good, given the power of computers of the time. More powerful OSes actually took a noticable amount of system time. DOS took essentially none, since it didn't do anything but basic disk and memory services.
The problem, of course, is the same problem we always face: it stuck around for too long. Systems advanced and it became trivial to run a more powerful OS, and thus highly desirable, but DOS stuck around since so many things were DOS based.
However don't think that it's simplicity made it bad, that was actually one of the attractive things about it. An 8086 system is really, really slow and had very little memory. It was desireable to have all the power and memory possible available to the application. You wouldn't want to try somthing like a modern Linux kernel on it. Even if you could hack it to work, it would use up all the system resources just doing it's thing, leaving nothing left for software.
Let's review some interesting facts:

1) Patterson sold his QDOS to Gates for $50,000, whereas Kildall sold his company to Novell in 1991 for $120 million, according the Oct/2004 BusinessWeek article (link:http://www.businessweek.com/magazine/conten
2) In his defamation suit, Patterson is asking for $75,000, plus court costs, per the Register piece (link:http://www.theregister.co.uk/2005/03/03/msd
3) The Register article includes a photo of Patterson's 86-DOS (QDOS) manual with the word, "Programmer", misspelled on the manual's cover.
There is a movie somewhere in there, but it's definitely not about ambition.

If sofware patents were available back in the day that both Microsoft and Apple were doing their thing (Apple, it's revolutionizing, and Microsoft, its copying), I dare say that neither would be around in its current form, if at all. All of the ideas we see today, in their various forms of implementation were based on something. The software patent fiasco is quite similar to the copyright fiasco - all of the fledgling companies that made it big without copyright extensions, the DMCA, or software patents, have now raised the barrier of entry to some rediculously high level. We all lose, of course.
Gary Kildall eventually died in a bar, but many (including myself) would say that Bill Gates drove Kildall toward suicidal drinking, which lead to him being killed in a bar with other drunks.
[...]
By contrast, Kildall did not even get the fame, i.e. the recognition that he deserved. Ask any Windows/MS-DOS user who Kildall is, and she will scratch her head with ignorance. If I were in Kildall's shoes, I would have been bitter every day of my life and would have probably committed suicide too.
I think that saying that Kildall was driven to suicide by Bill Gates is a stretch. I know of Kildall's story, but I really can't bring myself to shed too many tears. Kildall was still rich by the standards of most of us. He has successfully founded Digital Research. There were many innovative and interesting things that Kildall could have done, either at Digital Research or on his own.
You have the right to decide to kill yourself if you were "robbed" of the massive wealth and fame of Bill Gates (you make the point that it is both, not just one that is the fatal poison). In this case, I feel sorry for both you and Kildall in holding such egotistical world views.
Money may not buy happiness, but it can buy freedom. The fact that Kildall is not recognized for a crappy little operating systems like CP/M and DR-DOS is really no surprise. Looking back on CP/M, MS-DOS and DR-DOS all we can really say is "thank God we can use real operating systems like UNIX, Linux and even Windows NT/XP". Xenix and the early UNIX operating systems were far better and ran on machines not much more powerful than the Intel 286.
Instead of being famous for writing CP/M and DR-DOS Kildall could have used the money he made to do something really creative. But he did not. The tragedy in the story is that of wasted possibility, not lack of fame or an extra 40 billion dollars. The inability to take advantage of what fortune and hard work had given Kildall can be laid at Kildall's feet not Gates'.
I suspect that the real problem is that Kildall had a drinking problem and was in the wrong place at the wrong time (he died, as I recall, in a bar fight).
Who cares if Linus is or isnt a billionaire? He chose to make his project open source and use that business model to make his keep. There's no reason to feel sorry for him. Most of the geeks on this board would have nothing to write about if they didn't have Linus's work to sponge off of.
... I have this friend in Nigeria who needs you to hold onto some money ...
I suppose you also believe the old lie that Apple created the mouse driven user interface and claim MS stole from them, while ignoring where it really came from?
Give me a break. This is just more griping about why you hate the guy on top.
If more of you would stop the griping, and instead work on being on top, technology would advance 10x faster.
You were ripped off? how? did you invent 'happy o's' cerial right before 'cheerios' hit the market? 9 times out of 10, the 'ripped off' guy is a fool who gave away his idea/money when everyone else would have known better.
Which reminds me
George Bush + Linux = "I will not let information get in the way of the fight against Windows"
MS-DOS dominated the market for one reason and for one reason only -- IBM chose it as the main OS for the PC. Since there were so many low-level compatibility issues with early PC clones, IBMs competitors had to copy the PC in painstaking detail. That included copying IBM's mistakes -- the biggest of which was using one of the worst OSs ever made. Not by today's standards, but by the standards then.
Linux Torvalds however, quite blatantly made Linux borrowing many ideas from the Unix systems of the time, and he's heralded as a geek hero of our time. Don't get me wrong, I'm not bashing Linus in the least. I think he did well, and I think that Patterson did equally well creating his workalike. Kildall's arrogance cost him the IBM contract because someone else implemented a cheaper version.

With DOS 2.0, directories were finally possible. Remember - DOS 1.0 couldn't do directories. So, DOS 2.0 virtually copied the related parts of the UNIX C API with open(), close(), read(), write(), and ioctl(). At this time, there was no technical need to do that because DOS wasn't even written in C (the first release written in C was DOS 4.0 which bloated the installation media big time as most of you will remember), so they did it just for the heck of it. So - DOS 1.0 replicated most of CP/M's APIs, and DOS 2.0 added UNIX APIs. Compare this to SCO's ranting that Linux allegedly copied UNIX and you get an idea of the mind set of certain people.
.COM memory footprint? Ever parsed a command line from there? Duh. CP/M stuff.
So - The IBM PC used Intel CPUs that suffered from CP/M backwards compatibility (64K segments coming from the Z80 / 8085 era), and never overcame it, since even the very latest Pentium IV CPU boots up in the so-called real mode which mimicks an 8086 whose address space is segmented in 64K CP/M compliant address spaces; and MS-DOS copied the related 64K APIs. Remember the program segment prefix, i.e. the first 0x100 bytes of a
Had IBM chosen the M68000 and a better OS, many programmers wouldn't have gotten grey hair. Near pointers? Far Pointers? 5 different memory models in C or pascal? C'mon. Flat 32 bit address space, 1979. 68000 Amigas and Ataris were _way_ ahead of MS-DOS PCs at that time, but they did not manage to enter the office computer realm which made them fail economically. Today the PC market isn't office realm driven any more. How the world changes... . Anything else?
