- OSF/1 1.0 was released for general distribution on December 7 1990.
- There are no problems that I know of that has prevented it getting off
- the ground and I was one of the development team. In fact the project
- slipped only 2 or 3 weeks from its original ship date which is pretty
- impressive for a project of that magnitude I think.
-
- At the general release announcement the sponsors endorsed OSF/1 and many
- (including IBM) announced that they would be using OSF/1 as part of
- their operating system technology. The final IBM product could well be
- called AIX but that is their perogative and a marketing decision I would think.
-
- To question 1, OSF, the company, was formed in May 1988. As I said,
- OSF/1 has already shipped and your information about IBM is incorrect.
-
- OSF/1, simplistically, is the integration of Mach 2.5 microkernel and
- BSD 4.4 but there has been a significant contribution of technology from
- various sources, IBM, Mentat, Secureware, Encore, to name a few (I
- apologise to those I have ommited), and of course OSFs own development
- group. There is a small amount of AT&T System V.2 code in the kernel but
- not much and it is well isolated.

-
- As far as I am concerned there is no competition. Both systems support
- the standard interfaces (POSIX, FIPS, XPG3, ANSI-C, etc) so with respect
- to strictly conforming application portability the two systems should be
- identical. Obviously there are other differences, for example in the
- area of multiprocessor support, threads, dynamic configuration, etc but
- I will stick my neck out and guess that neither system will be "chosen"
- by any standards body as the one and only true system.
-
- The current status is that OSF/1 1.1 is already under development and
- likely to be available sometime in the next 12 months or so, I don't
- know the exact ship date. The system today has already been ported to
- more that 8 different architectures, including a MIPS R2000, National
- Semi 32532, Motorola 68030, Intel 80386 and I860, Fairchild clipper and
- more, I forget them all.
