We've been told by the NeXT people, that source for the Mach OS will not be available from NeXT, which, in my opinion is a bad move from NeXT. The argumentation was something like "we don't want people to tinker around in the kernel, probably making it so incompatible that sone software won't run anymore". I don't think this argument counts for academic sites, who would not release what they've changed, but rather use it for education. I for once don't know another real life system that uses mach, so the NeXT would be quite a good system for the purpose of looking into a mach system. Sorry if this has been discussed already in this group, i don't normally read it. Can someone comment on this ? -- Toerless Eckert | /C=de/A=dbp/P=uni-erlangen/OU=informatik/S=eckert 50GB/M limit: NO MERCY | X.400 ^ Internet> eckert@informatik.uni-erlangen.de

I have the Mach source code on the product list. It has a rather steep price tag though. This is most probably due to the AT&T licencing required to distribute the source... Anyone got 10k$ to spend?

Several companies sell "real life" systems running Mach. BBN ships
Mach on their Butterfly, as does Encore on their MultiMax. MtXinu has
been selling it to folks with VAXen and Sun-3s. And, beginning in
late January, they'll ship a binary distribution for AT-bus 386 boxes.
That's just off the top of my head, and I likely forgot some.
As far as I know, all the other Mach vendors besides NeXT at least
offer the option of a source license, albeit for a hefty fee if you're
not an educational institution.izumi@fugitive.berkeley.edu (Izumi Ohzawa) (12/27/90)

The following is from a price list generated by NeXT for UC Berkeley departmental purchases (dated Sep 28, 1990 15:52): Product# Desc List Price UCB Price N5514 NeXT 2.0 GNU Source Code $150 (Q1) $98 on Floppies (not in Fall 90 list prices) N5515 NeXT 2.0 Mach Source Release $10,000 (Q1) $5,000 on Floppies (not in Fall 90 list prices) The fee is quite hefty even for the educational institution, but at least NeXT seems to be offering it.
