The president of Zeidman Consulting which is a leading provider of consulting and expert witness services for intellectual property litigation, Bob Zeidman decided to offer a $100,000 reward to anyone who can simply find and prove that the tech giant Microsoft copied MS-DOS source code from DRI’s CP/M source code.

Find This Secret Command In MS-DOS Code To Win $100,000 Reward

MS-DOS was born in 1981 when Microsoft made an operating system for personal computers range of IBM PC. At that time, Microsoft bought the rights to QDOS, also known as 86-DOS, 1 of Seattle Computer Products, which was developed by Tim Paterson and began working on modifications to meet the requirements of IBM.

The first edition, MS-DOS 1.0, was introduced in 1982 and the version 2 included with IBM PCs which was known as PC-DOS. Although MS-DOS and PC-DOS were developed by the tech giant Microsoft and IBM in parallel, but both the products were separated over time.

MS-DOS is an operating system for computers based on x86, it was the most popular member of the family of DOS operating systems from Microsoft and the main system for personal computers Compatible with IBM PC in the late 1980 and mid-1990, until it was gradually replaced by operating systems featuring a graphical user interface, in particular by several generations of Microsoft Windows.

As we all know that the MS-DOS-powered PCs were soon gained a huge mass of success and popularity, which deposed DRI as the chief maker of operating systems. But, later the American computer scientist and microcomputer entrepreneur who created the CP/M operating system and founded Digital Research, Inc. Gary Kildall communicated the tech giant IBM and negotiated a higher license fee compared to MS-DOS, offering CP/M on IBM PCs. As a consequence, more people bought cheaper PC-DOS and Microsoft which continued to develop.

But, the American computer scientist and microcomputer entrepreneur who created the CP/M operating system, Gary Kildall accused that QDOS and MS-DOS were straightly cloned from CP/M, which infringed his copyright. Hence, DRI’s lawyers challenged that their forensic researchers found MS-DOS violated the DRI’s software.

Not only that, even it is also rumored that there is a secret command in MS-DOS which can print a legal copyright notice in the American computer scientist and microcomputer entrepreneur Gary Kildall’s name.

The president of Zeidman Consulting which is a leading provider of consulting and expert witness services for intellectual property litigation, Bob Zeidman decided to investigate both the MS-DOS and CP/M code to find out if there is any occurrence of copyright violations.

But, the president of Zeidman Consulting, Bob Zeidman not able found any proof or sign that the tech giant Microsoft copied CP/M from the Digital Research to create MS-DOS. However, the president of Zeidman Consulting, Bob Zeidman find evidence that system calls were copied. Here are all his findings which were published in IEEE Spectrum.

Hence, the president of Zeidman Consulting, Bob Zeidman is now standing behind his analysis and conclusions. So, now it was revealed that Bob Zeidman had an open consulting contract with the tech giant Microsoft in its dispute with Motorola.

So, now he will offer a $100,000 reward to anyone who can simply find and prove that the tech giant Microsoft copied MS-DOS source code from DRI’s CP/M source code, as well as he will also offer another $100,000 reward if anyone can simply explain the source code which has secret command in MS-DOS that can print a legal copyright notice in the American computer scientist and microcomputer entrepreneur Gary Kildall’s name.
