Hello all, a new member here.
I?m in the UK where I?ve lived for 17 years now. Before that I lived in
Canada.
I got my computer bug as a kid playing with VIC20, TRS-80, APPLE ][ and a
mainframe. Presently I work as a .Net programmer mainly doing ASP.Net. Most
of the old hardware I had stopped working for one reason or another and was
binned ? my Dad didn?t like clutter. So I?m surrounded by laptops and a
couple of older machines which used to run the network in the office.
I?ve started looking around for some vintage machines that I used at Uni.
Sparcstation, NeXT Cube are the ones I used the most.
One machine that I would very much like to have is a SUN Sparcstation as
I?ve some old projects that I did at university which I?d like to carry on
working on (also to show my kids what I did at Uni) If anyone on here is in
the UK and has a Sparcstation 1,2,4,5 I?d be interested. If it has the ??
drive than I?d be interested in that too. SunOS would be OK as that?s what I
used. I am tempted in a NeXT but my project used X11 and a library called
InterViews which I think will only work on X. Maybe someone can clarify
that.
Anyway, enjoying reading the posts and happy to have found you.
Salik.
I just listed one of my TU55s on eBay
I have a second one available in a rack with a TC01 avalilable for pickup in Fremont, CA
that I'm accepting offers on.
I'll be in Chicago for a week soon for a work event. Limited time for
myself but I'll have some time Sunday to maybe Uber around. Any suggestions
or cool spots for a computer collector to hit?
I see a museum of broadcast communications is close to where I'll be which
may be neat. Not sure if there are any used stores that might have vintage
computers but always willing to try.

Not quite! Sun was a participant in creating the OpenStep standard (the NS class prefix stands for ?NeXT/Sun?) and *created their own implementation* of OpenStep for Solaris. (Just as GNUstep is an independent implementation of the OpenStep spec under the FSF umbrella, and OPENSTEP/Mach and OPENSTEP/Enterprise were NeXT?s implementations.)
OpenStep Solaris was released, both the user and developer environment, and you should be able to find them today and install them on Solaris 2.5 or later. I think OpenStep will run on everything through Solaris 7 or Solaris 8, but at some point it stopped working because it required Display PostScript in the window server.

Indeed, that was post-OpenStep; they weren?t buying companies like Lighthouse to get a suite of applications for OpenStep Solaris, they were buying them to port their stuff to Java (since Java was based rather heavily on Objective-C, and some aspects of the Java frameworks? designs on OpenStep).

Wow, how important little words are!
The URL for the SFGate article is misleadingly
"...Bay-Area-locations-Frys-Electronics-closed"
... which is wrong.
The CCtalk thread is
"One of Bay Area's last Fry's Electronics stores closes"
The original SFGate article's title (click on link above to see) is:
"One of Bay Area's few Fry's Electronics stores closes"
Each means something different. ("one of...last" is more dire than "one of
...few").
Isn't English interesting?
Keep that in mind while reading political reporting, too :)

Nope, Mac OS X 10.0 was significantly upgraded and based on Mach 4 and BSD 4.4 content (via FreeBSD among other sources). It was NeXT that never got beyond Mach 2.5 and BSD 4.2. (I know, distinction without a difference, but this is an issue of historicity.)
I think only some of the changes from Mach 2.5?3?4 made it into Mac OS X Server 1.0 (aka Rhapsody) so maybe that?s what you?re remembering.

It was the original Linux port for NuBus PowerPC Macs at least. It was never really intended to ?get very far? in the first place, it was more of an experimental system that a few people at Apple threw together and managed to allow the release of to the public.
MkLinux was interesting for two reasons: It documented the NuBus PowerMac hardware such that others could port their OSes to it, and it enabled some direct performance comparisons of things like running the kernel in a Mach task versus running it colocated with the microkernel (and thus turning all of its IPCs into function calls). Turns out running the kernel as an independent Mach task cost 10-15% overhead, which was significant on a system with a clock under 100MHz. Keep in mind too that this was in the early Linux 2.x days where Linux ?threads? were implemented via fork()?
I don?t recall if anyone ever did any ?multi-server? experiments with it like were done at CMU, where the monolithic kernel were broken up into multiple cooperating tasks by responsibility. It would have been interesting to see whether the overhead stayed relatively constant, grew, or shrank, and how division of responsibility affected that.
