MS-DOS Not Stolen, New Forensic Analysis Concludes
theodp writes "Challenging earlier assertions that Bill Gates got the rewards due Gary Kildall, a forensic analysis conducted for the latest issue of IEEE Spectrum concludes that the landmark MS-DOS operating system which Bill Gates and Microsoft licensed to IBM was an original piece of work, not stolen goods. Using his company's CodeSuite forensic software, Bob Zeidman said he found no evidence that QDOS or MS-DOS was copied from or was a derivative of Gary Kildall's CP/M. So, what do you think of Microsoft expert witness (pdf) Zeidman's "if-the-codebase-doesn't-fit-you-must-acquit" arguments?"
I think it's interesting only as a matter of curiosity at this point.
Actually, it's a fairly typical Microsoft attempt at a derivative: a copy of the superficial features on top of an unholy mess that shows that they don't understand the deeper concepts.
"I know I will be modded down for this": where's the option '-1, Asking for it'?
From your link: "What is the evidence, then, that QDOS was a derivative work – a rip-off? The answer lies in the API, which describes how software can call up the underlying operating system and make it work for the user. The first 26 system calls of MS-DOS 1.0 are identical to the first 26 system calls of CP/M."
Yeah, just like Linux and WINE are rip-offs. The need to map system calls by number and not only name was of course due to the fact that the actual calling mechanism worked by number. However, the IEEE article is still strange, since the matters described are already settled. On the other hand, the legend of DOS being stolen and not only a clone lives on, in some places.
Windows? -> copy of MacOS Classic
Any more than Android or GNOME or KDE is a copy of Apple products?

Alternate summary: CodeSuite found not to work as forensic software!

The PET was a much better design. And back then, it was all good... in fact, Chuck Peddle (inventor of the PET and the MOS 6502) actually helped Woz on some critical issues to get the Apple I up and running. But Peddle had a whole system approach, thus, all the other chips Commodore made to support the 6502. If you look at the Apple I/][ or may of the other early personal computers, you usually see a Microprocessor, some memory chips, and a vast sea of SSI and MSI parts from the TTL databook. If you look at early Commodore machines, you find all sorts of integration.
But there's a vast difference between "inspired by" and "copied". And even then, in layers. Steve Jobs saw the Xerox Alto and got inspired. Apple didn't really copy the UI, they actually left out some of the good stuff. And of course, the OS they created was vastly inferior, and the internals had nothing to do with the Xerox system. Microsoft did actually borrow some of Apple's stuff, but they's because they actually did exchange code. Most of Windows had nothing to do with MacOS, and the OS design was not something any experienced OS designer would have some up with (eg, the OS treating an application as a series of callbacks)... and that's not even counting all of the serialization Windows did in Win32 to prevent real multitasking.
Windows NT, on the other hand, was directly inspired by VAX/VMS (via Dave Cutler), but also ran a POSIX API layer from the get-go. But that was a standard by then, so no really a "copy" of UNIX anymore.

Did Bill Gates pay $50k for QDOS? Or did he not? It's pretty simple...
If he did, it wasn't stolen, he owns it.
but this is because this was the early eighties, the era of Pacman lawsuits, to be followed a few years later by Apple's infamous look and feel suits against DR and Microsoft/HP.
Oh how the times have changed.

Well of course they wouldn't have sold the product as cheaply if they had material knowledge of a pending deal the buyer had, but unless there was some disclosure requirement in the purchase agreement then they should have been told to GTFO.

Insider trading isn't "considered" illegal, it IS illegal - there is a law against it. It is illegal because that is the rule for being a publicly traded corporation - everyone gets info affecting the price of the stock at the same time. If that were not the case, people inside the company could profit at the expense of the other shareholders.
None of that has anything to do with private dealings. In fact, it is likely that Gates was under an NDA and could not say anything about the IBM deal, as IBM had not yet announced the PC. Divulging the IBM deal could not only have insider information ramifications, but remember that at the time IBM was under a consent decree that prohibited them from 'pre-announcing' anything.
