I can't get the sim 2.3d to boot ultrix 3.1 or xenix or anyother boot tapes
in the uhs's archive. I have compiled the pdp11 emulator with gcc-3.4.6. I
am also interested in the OS Tim Berners-Lee used to write his first
browser. VMS on a VAX machine I have read. Is there anything like this in
the archive? A VAX emulator and VMS OS?

I've heard of a free VAX emulator called SIMH/vax, and a commercial
one named Charon-VAX (or something), but I've tested neither.  If you're
adventurous enough, you might consider real VAX hardware: the VAXstation
3100 and 4000 series models can be had at reasonable cost, and are not
larger than a desktop PC.  As for VMS, at least the recent 7.x versions
are available more or less freely for hobbyist use.

By the way, are there releases of Xenix that run on PDP-hardware?
I've only ever heard of PC (8086+)-based ones.

Tim Berners-Lee developed what became the WWW, server and browser, on
a NeXT computer running the NeXTstep OS.  There is not a whole lot of
public knowledge about the internals of the NeXT hardware, which makes
it difficult to write an emulator for it.

There is a slowly progressing effort to port NetBSD to NeXT hardware. 
Also, the last few releases of NeXTstep and OpenStep would run either
on NeXT hardware or selected x86 hardware.  Somewhere there is a
writeup covering the subject of running OpenStep on the VMware virtual
machine.

None of this is VAX, nor is it any other hardware covered by SimH.

There were. On 23 March 2002 Martin Crehan started a thread on this  
list, including a cite to this Slashdot posting: http://slashdot.org/ 
comments.pl?sid=29920&cid=3213453

I would link to the thread, but the search seems broken (http:// 
minnie.tuhs.org/cgi-bin/pups.cgi).

Apart from the PDP-11 version mentioned there, I am also aware of the  
Lisa XENIX port (68K).

In my memory, it seems that Xenix was originally done for the Motorola
68000 then ported to the Intel x86 architecture.  The first real "Unix"
I ever ran, by the way, was Microsoft Xenix on a Motorola 68000 based
Tandy 6000.  I do not believe that Xenix *ever* ran on PDP based
hardware.

My 1985 PDP11 Software Sourcebook lists XENIX for the PDP11 as
being available from SCO.  It also lists Venix as available for
other than just the Pro.

You mean SINTRAN III/VSX?

    Is there quite a disagreement in what the first browser was?

Well, there seems to be some issue with ENQUIRE, Tim Berners-Lee's first foray 
into hypertext, but considering that that program may not have used a 
protocol named HTTP, a markup language named HTML, nor a spatial metaphor 
called the World Wide Web, it may not count.

The first time, AFAIK, that the terms we now know came together was in the 
browser built for NextStep.

I think if you're going to count ENQUIRE you ought to count some of  
the other earlier hypertext systems.
