Peter,

I can't get the idle detection to work - Simh hogs the CPU.  I am using set
cpu idle=netbsd.

 

Try the simh_vax_cpu_idle patch I wrote. It is on sourceforge under the
unofficial patches folder.
   
Thanks for the idea.  I looked and couldn't find it.  Please could you 
supply the information I need to find the patch?  I looked at 
https://sourceforge.net/projects/simh/ and then did a Code-Browse 
CVS. There are a lot of directories there - which one contains your 
unofficial patches?

I've been maintaining the sourceforge stuff... And I've been collecting
patches from people or posts, and putting them on the site, as before that
I've been providing builds for anyone outside of the linux/win32
environments.. (speaking of which work FINALLY got me some OSX access so
I'll be updating with some 10.6.3 binaries...!).

Send me what you have, and I'll add it to the sourceforge page.

worst case I do kind of have a wiki on:

where I've even tried to provide some access to legacy systems, along with

The only thing I would suggest is a way to provide some 'image' uploads for

Then that could be a dealbreaker. Is it really proposed here that the

Re: [Simh] SIMH future releases / Sourceforge project

2010-09-02 Thread Jason Stevens
Well the big thing that is needed is binary builds for other platforms, and
some kind of a 'test suite' to really verify that these emulators work
correctly.

I've done what I can, but honestly I don't know all that much about these
older platforms  Maybe with a resurgence of interest we can finally get
at least
one OS test case for everything?

Sourceforge is at least 'established', and it does provide world wide
mirroring, and hell it's FREE which IMHO is a 'good thing'.  The other nice
thing is that you don't need any weird tools to download any release, os or
patch, as they are all available to any HTTP 1.1 compliant browsers,
although they recently have gone the path of AJAX hell... but you can still
figure out some kind of direct link from any browser.

If anything I think the 'google' effect to the soruceforge thing is pretty
low, but then how many SIMH users are there really out there?

Is it even worth asking for a census?  Am I just thinking over the top???  I
judged platform priority from the old 3.7-3 release of SIMH when I started
uploading what I could, and I was kind of surprised that it went
win32,MS-DOS,Linux,OSX,NeXTSTEP

At any rate, for the current
MS-DOShttp://sourceforge.net/projects/simh/files/simh%20binaries/3-8.1/simh-3.8-1_MS-DOSi386-exe.zip/downloadlcd
these are the following platforms I can verify to some degree:

*Altair (CP/M,ALTDOS)
*Altair Z80 (CP/M)
*HP2100 (Basic)
*ID32 (Unix6 7)
*Nova (RDOS)
*PDP11 (Unix1 restoration)
*PDP8 (OS8)
*SWTP (FLEX...? I forget how to even get beyond $ prompts)
*VAX (Quasijarus BSD)
*VAX/11780 (BSD 4.2)

Naturally things like VMS aren't free, so we can't put them online, but
things that *are* free I'd love to be able to include some kind of basic
users guide, to get to know the machine/platforms It's a steep curve for
anyone who's never used these old machines before...   And like everything
else on the internet, things seem to show up, then suddenly disappear, and
even with large hiatuses on my own stuff, sourceforge has kept things around
which is nice.


Oh well I see I'm rambling like crazy so I'll stop for now, but that's my
$0.02 ..

eh finalizing the palette can be rather problematic, because 
actually the ancient Latin wisdom de gustibus non disputandum est is 
de gustibus *et coloribus* non est disputandum (meaning, not only the 
taste, but also the colour spectrum should be not discussed, being tied

[Simh] DECtape marks issue????????

2010-09-02 Thread Rich Alderson
 Date: Thu, 02 Sep 2010 20:08:01 +0200
 From: dott.Piergiorgio dott.piergior...@fastwebnet.it

 (looking to the DECTape marks issue, for example)

What is the DECtape marks issue?  The DECtape emulation in SimH does not
simulate the mark track on a DECtape, so I don't understand how there could
be a DECtape marks issue.

I suggested to Bob several years ago that the DECtape representation could
be made more realistic (and thereby more flexible).  His reasonable answer
was to point out that I could do the implementation, should I choose to do
so, and submit it for everyone's review; since I am not a C programmer, I
have never had the time to do that.  (Macro-20, sure.)

I'll outline my original vision, and my present simplification, and if you
(or anyone else) wants to pursue it, I'll be happy to provide insight into
the working of DECtape drives and controllers.

Represent the frames on a DECtape as 8-bit bytes; the timing tracks are
implicit in the order of the bytes in the resulting file.  Represent the
mark tracks with bits 0 and 7, one the inverse of the other (as a nod to
the automatic inversion of bit sense in a Read Backwards operation).  The
data tracks are 1 = bits 1 and 4, 2 = 2 and 5, and 3 = 3 and 6, where bits
1-2-3 are conjointly inverted with respect to bits 4-5-6.  We ignore the
fact that on a physical DECtape, 5 tracks' worth of data is redundantly
recorded on 10 tracks (T M 1 2 3 1A 2A 3A M T).

This can be simplified if we drop the inversion, and represent each frame
in an 8-bit byte where the mark track is bit 0 and data tracks are 5-6-7.

The controller (555, TC01, TC02, TC08, TC09, TD10, TD8E, TC11, or TC15)
is responsible for assembling 3 bits of data at a time into 12, 16, 18,
or 36 bit words and putting it into the CPU or memory, as appropriate.
That's where all the work is.  There's also the question of other brands
of computer (Data General comes to mind) and their controllers, as well.

Creating realistic DECtape emulations for SimH could turn into a cottage
industry.

But let's return to the question:  WHAT DECtape marks issue

[Simh] OSX builds

2010-09-02 Thread Jason Stevens
ok now that I've finally gotten my hands on 10.6.3 I've built
i386/x86_64/ppc7400 builds for everything I tested what I could and it
seems to work.

If anyone else can verify so that I don't have a repeat of that 10.4.5
disaster...

Hello!
One way of looking at it. I do not believe that the complaints that
have been aired concerning the mess that Source Forge is evolving into
are relevant to us.

If anything it is the problem of the users who are allowing it to
become so much garbage.

The next step will be to create binaries for the PC, both Linux and
Windows. Include networking support. I'm not sure how the BSD faction
will be allowed to come up next. That is everything else but OS/X and
Linux who're covered under different banners.

BSD faction members like NetBSD for example. If we can get NetBSD for
the Vax to run properly on SIMH/VAX then some fifty percent of the
issues faced over there can be resolved.

Re: [Simh] OSX builds

2010-09-02 Thread Jason Stevens
I've always been under the impression that Net/Free  OpenBSD users either
use their local package system to get stuff, or are capable to build their
own binaries...

Otherwise, on the sourceforge page, when it detects your OS, it should
shuffle you to the appropriate OS.. It has hooks for OSX, Solaris, NetBSD,
Linux  Windows... And I've now got binaries that cover all of those for the
'normal' non networked build...

As for the NetBSD idle, it may involve reverting the idle code changes
between 3.8-0 and 3.8-1 ...

But even then I'd feel very hesitant to roll that into any mainline builds.

I guess I'll have to download some miniroot or something for NetBSD to watch
it idle.  I assume the MicroVAX II is where everyone is using this

Re: [Simh] SIMH future releases / Sourceforge project

 The quality of the software and the ultimate decision on released

 And a mighty fine job he did!

And then later, Wilm Boerhout wrote:

 This discussion is not (was not originally) where it's stored (although 
 others above have pointed to viable alternatives) but who is 
 responsible: Bob Supnik or the open source community. I vote for Bob.

Just to be perfectly clear, I am a HUGE fan of Bob Supnik's work on SIMH.  
Booting OpenVMS on SIMH still brings a grin to my face when I think back about 
wrestling with a shiny new MicroVAX 2000 and loading MicroVMS 4.5B from about 
80 floppy disks back in 1989.  Bob's (largely single-handed) vision and 
dedication is what brought SIMH and the retro-computing it allows us all to 
enjoy, to the point where it is today.

Having said that, I also don't want to see SIMH become stagnant if Bob's 
available time to devote to SIMH may become (or perhaps already is) limited.  
And I don't want to see multiple forked versions of the code start to spring up 
because people are impatient waiting for patches to be incorporated in the 
mainline, or for their favorite new whiz-bang OS to be supported as a host.  I 
am not voting against Bob, but rather, my vote is for SIMH *and* for 
maintaining it to the same high standard as Bob intended.  If that means having 
a core team that ensures Bob's blueprint is followed, fantastic.  If Bob wants 
to tell us all to take a hike, I've got to respect that too.

Bob, if you're out there reading this thread, your devoted SIMH fans would love 
to hear your thoughts !!!

Jason

 Sourceforge is at least 'established', and it does provide world wide
 mirroring, and hell it's FREE which IMHO is a 'good thing'.  The other nice
 thing is that you don't need any weird tools to download any release, os or
 patch, as they are all available to any HTTP 1.1 compliant browsers,
 although they recently have gone the path of AJAX hell... but you can still
 figure out some kind of direct link from any browser.

All of this is true of github, codeplex, and google code to name three
alternatives just off the top of my head.  There are others I'm sure.

I voice my preference as someone that formerly hosted open source
projects on sourceforge, attempted to interact with the owners of that
site to address what I (and others) perceived as its shortcomings, was
basically rebuffed and eventually decided to move to another open
source project community site.  (I chose codeplex, but that has no
real bearing on the lameness that sourceforge has become.)

I'm not an active SIMH developer, so I provide my opinion as food for
thought, but its not a compelling reason to do anything either way.

Re: [Simh] NetBSD5.0.2

2010-09-02 Thread Jason Stevens
Well getting back to the start of the thread, what I've done here is
regressed the idle code to include an OLDVMS option which set the idle
timings and hook to the old pre 3.8-1 levels, allowing things like 4.2 BSD,
and other BSD's to idle correctly.

Note that this is *FAR* from tested, as I just built it under MinGW and
booted up the NetBSD 5.0.2 miniroot, and as soon as it's done it's thing
it'll idle on my laptop (windows 7 , x64) at 0%

The patch is here:

https://sourceforge.net/projects/simh/files/Unofficial%20Patches/3.8.1/regressed-vax-idle.zip/download

Although I can verify that it seems to 'work' right on windows, when I
compile the same patch on OSX I get 50% cpu utilization

Oh well I guess it's worth something.
