Some facts to clear up some misconceptions: 1. NT now stands for "New Technology". It did not originally stand for "New Technology", but what it used to stand for had nothing to do with VMS-. Dave Cutler, the software "father" of VMS and DEC (as well as lesser-known projects), is the chief architect for NT. 2. The researcher in charge of the Mach project, Rick Rashid while at Carnegie-Mellon University, currently is the Director of Research at Microsoft. A number of people involved in Mach at CMU are in the research group. Neither Rick nor his group has been directly involved in NT, although they have provided feedback. They arrived at Microsoft well after Cutler's team was in place. 3. NT is a micro-kernel architecture with a small object manager in its executive. One big difference between the Mach and NT architectures is the use of the port abstraction in Mach, which NT does not have. 4. The product "Windows 3.1/NT" is the NT micro-kernel hosting a number of user-level subsystems including a 32-bit and 16-bit Windows API, and running on a variety of CPU architectures and SMP machines. 5. A nice but seldom-described feature of NT is its definition of the Hardware Abstraction Layer (HAL), while allows significant innovation on the part of hardware vendors without requiring software changes in the NT kernel. 6. Windows 3.1/NT is an unreleased product. An essentially unrestricted developer's release shipped some time ago. -- Edward Jung, Software Architect edwardj@microsoft.com Advanced Systems, Microsoft Corp.
