[Simh] Cygwin and SIMH

[Gregg Levine]

Hello!
Has anyone every gotten SIMH to work using Cygwin? This presupposes
that the target may or may not include networking.

I am currently looking at the VAXes and a PDP11 to be named later.

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.

 I have to disagree with this.  Aside from those who wish to run ITS on
 SimH (or KLH10), there is a restoration project at Living Computer Museum
 to bring the KS-10 system MIT-AI back to life.  We currently have a second
 KS-10 running the ITS MINSYS installation, and I am working on building
 9-track tapes from the images which used to reside at ftp.its.os.org .

 Once the hardware is stable, we will put the system on the Internet for

 Interesting.

 I'm currently experimenting with 'ttylinux' (latest build)
 to work on a EPIA-1 board with a MOXA 4 channel serial card.

 This release uses kernel 2.6.34.6 and I use the i486 configuration
 file. I did build a simh package for it so it work within the ttylinux
 build environment. The  linux kernel runs in 8 - 12Mb, and uses busybox 
 dropbear for utilities  ssh connectivity.

 I also have modified the simh code in such a way that it can use real
 serial lines within the emulator, so you can use a real vt100 to
 work on. Both the console and a 8 port DZ-11 can be configured.
 i.e. 'set console serial=/dev/tty00:1200' (1200 is the speed) for
 the console line or 'set DZ map=0=/dev/tty01'

 The simh version I use is v3.8-1 and it contains only the pdp11 code
 in the build package.

 As a side note :
 I have the same version of that code including the real serial code
 running on my Unix workstation at the office, and I have a vt-525
 connected via an Edgeport usb to serial converter.
 It runs rsx-11m 4.4 with a 'show memory' display, for some week now.

 While I was reading that slashdot thread of people reminiscing about
 Linux in the late 1990's
 (http://linux.slashdot.org/story/11/03/03/006250/Reminiscing-Old-School-Linux
 ), I found mention of this gem... spkdoom.

 It's 2.7MB compressed, and setup as a UMS-DOS filesystem.  I know with
 it being Linux 2.0.33 makes it a tad stale, but it does perhaps give
 some hope for running a super minimal Linux system to run SIMH.  While
 the idea of a FAT drive may be a hindrance, perhaps the latter
 versions support FAT-32?  Maybe even NTFS?

 The whole thing is based off of Xdenu, which was some super minimal
 thing at the time to make a simple X terminal... so networking is in
 there.

 Anyways for those interested you can download it here:

 http://www.gamers.org/pub/idgames/utils/misc/spkdoom.zip

 This may be another way to a minimal 'bare iron' type of thing.

Hello!
Well I've got ttylinux being downloaded here. Can you supply the

Hello!
This is a long shot, but here goes, what, ah, platform was the
original DSK file created on? That is what is their copy of SIMH for
the Vax running on?

Next why not provide for us a copy of the methods used to initialize
the emulator. From that we may be able to advise you further.

And this is extremely important, did you build your own copy of SIMH
for this release of SUSE? Or was it built originally on a different
platform?

Oh and does the program run anything else properly? Other releases of
what the DSK blob you're trying to boot here, contains. It could be
our old friend VMS, or BSD or something we've not heard of before on
that DSK and so forth.

[Simh] Interesting problem in using the (new) VAX emulation code

[Gregg Levine]

Hello!
I am trying to use the instructions for installing (and then running)
NetBSD with the VAX emulation. Since it seems to be a bit of a SNAFU
for installing via CD, I decided to try and make use of the improved
networking code to fetch the sets via FTP and install that way.
However the installer is causing a strange dump effect. Here's a cut
and paste of what is happening:
 Status: Running
Command: progress -zf /targetroot/usr/INSTALL/base.tgz tar --chroot -xhepf -

What is interesting is that always happens that way. Even with a new
disk image being created. I did once manage to get the original one to
accept the NetBSD instructions and install the OS a while ago, but not
on this machine. Mark this is something running on a snapshot from
your collection, it is not what is being offered from the site.

Re: [Simh] cpu idle with NetBSD

 Hi Mark,

 I like the idea of splx(splx(7)),  but it might be good to make the level
 configurable.  Currently, the lowest software interrupt used on NETBSD is
 level 8 for softclock,  but conceivably another system (or a future version)
 might have an additional software interrupt level and make use of 7.

 Regarding your last paragraph, there are actually (believe it or not) still
 job postings for people with VAX experience.  Including various BSD's, not
 just VMS.

 There is a surprising amount of application software out there that still
 runs on vaxes,  but the cost of maintaining those machines must keep
 increasing.  And there is more support available for NETBSD (which can run
 4.3BSD a.out's) via the net or a company similar to Cygnus than there is
 for, say,  More/BSD, whose vendor disappeared years ago.  Replacing a Vax
 running that system with a simulator running NETBSD may make sense to those
 with a large investment in applications that run on their vaxes.

 Hi Chris,



 There were issues like this on prior versions of simh.  (V3.8-1 and
 earlier), which you are running.



 The latest (about to be released) version is v3.9-0-rc2 which has
 significant improvements to the idle implementation, including a solution to
 the issue you found.  My earlier comments were specifically referring to
 that new idle implementation for the VAX.



 The release candidate which is close to release is available at
 https://github.com/markpizz/simh/zipball/v3.9-0-rc1

 Save what that URL returns as a zip file and unpack it and build a vax
 simulator with networking support using:

    unzip –a zipfilename.zip

    cd markpizz*

    make vax





 The key issue with recent versions of NetBSD is that earlier versions of the
 OS had the vax specific idle routine within an assembler module called
 subr.S .  The simh idle logic detects the code which is implemented for idle
 in subr.S.  Meanwhie, newer versions of NetBSD don’t carry this assembler
 code anymore and a much more complicated sequence of things going on,
 essentially all from compiled modules (from a little examination of the code
 I’ve done).  The structure of the idle management has been adjusted to
 accommodate the features we have on modern system… (Everything Multi-Core,
 HyperThreading, etc.) with some low level tasks delegated to the idle loop
 as well (page zeroing).  There is one platform specific callout to
 “cpu_idle().  cpu_idle() is defined in usr/src/sys/arch/vax/include/cpu.h.
 It is defined to be a macro:  “#define cpu_idle() do {} while
 (/*CONSCOND*/0)”  A normal compiler wouldn’t generate any code for this
 macro.  If the macro instead was defined to be “#define cpu_idle() do
 {splx(splx(7))} while (/*CONSCOND*/0)”



 I have sent a message to the NetBSD vax mailing list with the above
 suggested change to the base source code.  Maybe it will get adopted.
 OpenBSD has similar, but different code but I’ll make the same suggestion
 there as well.  Maybe this will end up built into these OS builds….



 I come back to the question of why folks would want to run the new version
 of NetBSD on a simulated VAX when they can run a native one for their host
 platform which will be the same OS and be more naturally behaved.  If the
 point is merely to test to see if the OS still works, that’s great, but then
 you boot it test a few things and then turn it off.  Great idle support
 isn’t needed since it won’t be running continuously.

Hello!
Mike, what were you looking for when you clicked there? That's how his
resource presents use with zip files of his work. In fact if you were
to take a look at one of the GitHub offerings, you'd see a similar
method.

Next Question: Cygnus was glommed by Red Hat because of its interest
in eCos an interesting and sadly difficult to make work Real Time
Library, (Not an OS, they expect you to do all the work and they
provide the libraries, and the tool chains. It's up to you the user to
build the program that will run there, and eventually graft it into a
real OS. Although they did claim that it supported a number of
processors fully and did there become an OS.) however that part got
spun off years later leaving them holding the bag for the Cygnus tool
chains. The question is, What company were you thinking of? Please
explain off list.

Mark sorry for stealing your thunder, but I thought I'd explain what

[Simh] More on using the latest (stored in git) release of SIMH

[Gregg Levine]

Hello!
I (earlier today) attempted to install NetBSD-5 for the VAX into a
disk as described here:
http://www.netbsd.org/ports/vax/emulator-howto.html

I created a install file using this as a template:
load -r /usr/pkg/share/simh/ka655x.bin
set cpu 64m
set rq0 ra92
at rq0 netbsd.dsk
set rq1 cdrom
at rq1 /path/to/vaxcd.iso
at xq0 name-of-network-interface-on-host
boot cpu

From that I made some changes:
   load -r /usr/local/bin/ka655x.bin
set cpu 64m
set rq0 ra92
at rq0 /usr/local/vax-netbsd/netbsd.dsk
set rq1 cdrom
at rq1 /usr/local/vax-netbsd/vaxcd-5.0.iso
at xq0 eth0
boot cpu
After the system ran through its usual series of checks, I then
entered at the prompt:
boot dua1: (The three right arrows are my approximation of a VMB prompt.)

From there after a series of routines that can only be described as
typically appropriate for the VAX when running NetBSD, waited for the
installer to prompt me for language selection. English was chosen. I
then told it to configure the Ethernet connection. From there I
returned to the install methods. Installing from CD did not want to
work, it complained about how the disk was mounted or not mounted.
Instead I chose a network one. Everything seemingly worked until this
happened:

 Obviously that one breaking made it not possible to continue. I only
 need
 the VAX and PDP11 ones, now.

 This is a known issue with the v3.9-0 release.

 Since you only are interested in the vax and pdp11, you can build individual 
 simulators:

   make vax
   make pdp11

 Good Luck.

 - Mark Pizzolato


Hello!
I should also mention that I need them but built with networking
support. Especially the vax one. But now that I see the comment from
Dennis Boone, (Thank you!), I see the ones I need Good catch.

[Simh] Throttling and this release

[Gregg Levine]

Hello!
Was the throttle function included as part of this release of SIMH? I
finally managed to get NetBSD/VAX installed, but it managed to corral
the entire workload of the host at 100% of the CPU.

I want to throttle it back to about 75%.

[Simh] Networking and SIMH

[Gregg Levine]

Hello!
Okay so I've managed to install the VDE components and the PCAP
development components on my Raspberry Pi. Invoking make caused the
build system to choose the VDE components. Why? When both are
present I figured it would chose both rather then the one I'm not
familiar with.

In any case I know I can work with what the methods chose and
eventually accomplish what I am planning on doing with the appropriate
simulators.

 The build It is not an either or process.   It will build using whatever
 Ethernet transports methods are available on the local environment when the
 build is done and each of those may be available when running with the
 simulator you built.

 As I recall, when I did this on the Raspberry Pi, I didn't have to look
 for libpcap-dev for that platform, I believe it was packaged with the OS.
 If /usr/include/pcap.h exists AND libpcap's shared object is available on
 the system (i.e. if tcpdump works) that is sufficient to build (and later
 use at runtime) with libpcap support.

 You don't explain how you think it chose just VDE rather than both.  If
 you provide the output that make produced while building the simulator it
 will be more clear what capabilities are being built in.

 Meanwhile, to use one Ethernet transport method over another at run time
 will depend on several different goals.  You need to be running as root on
 any Linux platform in order to inject packets into the network using
 libpcap.


 You need to be running as root to even sniff packets with pcap.

Re: [Simh] ALTAIR thinko?

[Gregg Levine]

Hello!
Would the Octal reference for $FF be used because one of the authors
of emulator would be more familiar with those terms from working with
the one for the PDP-11?

I've seen the crowd courtesy the VCF and have a box here who's waiting
to be restored.

Oddly enough I came within a big something-else to own one (an Altair
or IMSAI or the Heathkit version) a long time ago.

 That was definitely true and how the HW worked [although the comment should
 have been 0xFF or actually $FF in Intel syntax - since the 8080s were
 defined in hex not octal like PDP-11s).  There was no non-existent memory
 trap for the bus, so the HW read the data back as 0xFF because of TTL
 floating to high.

 I do miss the Altair and Imsai machines in a strange sort of way ;-)

 Until they appear at bitsavers.org, you can use my link:

 The scans come in two versions: high quality and blackwhite:

 The HQ version is gray level and contains a true image of the micro fiches,
 after non-destructive contrast enhancement. It is the base for further image
 processing.
 Download path is ./fichescanner/hq/gh

 The BW version is compressed to black  white and aggressively optimized for
 size and letter quality. File sizes are 20x smaller than the HQ version. Its
 intended for daily use and OCR, but for some very problematic fiches textual
 information is lost.
 Download path is ./fichescanner/bw/gh

Remember the keyword in my presentation was "possibly".

And shortly after sending it, I realized it was for the other one,
RTS-8 not OS/8. (That was based on the discussions on that list you

was and still is, that of hardware.

I wonder if it was ever tested properly and even made to work with

I seem to recall that on another list, the subject what did DECnet
support caused a similar flurry of things to be discussed. Even a
partial discussion of that protocol over serial lines for either the

suggested.

But I suspect, sir, that you're right.

Re: [Simh] Panic while attempting to boot a NetBSD ISO

[Gregg Levine]

Hello!
Yes indeed. I saw that well after I sent off the message. The, ah,
render engine, for FireFox on Linux doesn't properly render the pages
for the NetBSD site. Why? That's asking for too much.

As I said, I'll try again later. But that is good advice. I should
mention that I'm returning to SIMH after a long (perhaps too long)
hibernation.

Re: [Simh] Panic while attempting to boot a NetBSD ISO

[Gregg Levine]

Hello!
Okay I've tried again to bring things up. This time remembering to
give it dua1: at the prompt instead of something else. It promptly
complained. I'll try one more time this time with the image in the
same directory as the boot script. I've also commented out the
firmware blob since you've commented that its already included.

Re: [Simh] Panic while attempting to boot a NetBSD ISO

[Gregg Levine]

Hello!
Same problem as before, again with the proper location for the CD as
the VAX emulation knows its there. The routines start as before then
at the prompt I enter boot dua1:. Then the simulation escapes back to
prompt for itself rather then a VAX prompt and that's where I'm stuck.

Oh and this is all happening with the code retrieved from GIT about
now. I'm going to update the store and start all over again. (Building
them.)

Re: [Simh] Panic while attempting to boot a NetBSD ISO

[Gregg Levine]

Hello!
Not yet. I only snagged the first three of the 5 series that I could
find. For example 5.1.3 worked as far as being booted from the stock
release. (Installation is next.) I'm going to try 5.1.4 and 5.1.5
next. Also 5.2 and stuff between them, and including your 7
suggestion.

And Mark? I'm interested in the differences between why the last known
release on the SIMH website worked as far as booting the CD image
goes, and what's currently inside GIT does not.

Re: [Simh] Panic while attempting to boot a NetBSD ISO

Hello!
I'm still not certain what's going on here. But I downloaded a copy of
the last known release from the website, and built it. And then
followed the procedures. In this case it was to try and boot an image
of 5.1.3 and it worked. I'm going to need to spend more time on this.

Mark when you have the time can you look into what might be going on
there? (Your choice of hosting OS)

Re: [Simh] Intel's PL/M-86, ASM86 and iAPX-86 Utilities source code

[Gregg Levine]

Hello!
And I remember trying out an extension to iRMX-86 which would work
with MS Windows 3.11. (Or Windows 3.0) It was an interesting idea, but
I never got it to go anywhere.

It would be interesting to track down the whole business.

Re: [Simh] pdp11 and unix

[Gregg Levine]

Hello!
Let us not forget the ongoing legend that there is one Federal agency
all of us want to see out of business who runs older systems, and in
fact might be using punch cards for their methods of data entry.

And there is still yet another one where the equipment is old enough
to vote, and helps us fly planes everywhere.

I'll leave it as a lesson to the group to figure out who they are.

Hint: Dave W. May already know who the first one is under a different name.

Re: [Simh] pdp11 and unix

[Gregg Levine]

Hello!
Version Zero was hand coded on a PDP-7. Included the necessary tools
to make the tools, that is the components we use now on the ones on
the PDP-11 to write programs.

As I understand it, but I believe there are people on the list who
know more then I do,and can chime in; the gang at Bell Labs started
with a spare PDP-7 that one of the group there felt lonely for. Once
they were ready to move past Version Zero and move towards the one we
know it became necessary to move the code to a PDP-11, and from there
they probably had to redo a heck of a lot of things, but oddly enough
it all worked after a fashion.

I've seen Assembler output from a PDP-11 someplace. It's always
reminded me of a frustrated 6502 microprocessor or a 6800 series one.
But only just.

As I said folks, if I've left out anything or did not get the full
story done right please feel free to chime in.

 When they did this with floppy drive sounds in the Commodore 64 (and
 others) emulator VICE, I was skeptical at first. But soon I had to admit
 that getting feedback like how fast the heads were stepping, or if the
 floppies were rotating, was a very effective addition.

[Simh] Oddball platform as SIMH/pdp11 host

[Gregg Levine]

Hello!
Can the SIMH project materials, such as the PDP11 emulator be built
and even managed on an Intel Galileo gen 2 ( or the gen 1) platform?

This is an Intel QUARK SOC platform leveraged such that it's output
and input is in the form of the Arduino families.

However networking is already physically present, and there are two
serial ports, the main one, and the classic one found as digital pins
0 and 1.

Ideally what I'd like is to have the thing pose as an appropriate
PDP11, and deliver its terminal via the second serial output.

For digital I/O i'd eventually like to tease the thing to allow its
eight regular pins to become the ones for an emulated DR-11 or DR-11C
board.

I do know that the latest release of the E11 product does make use of
one company's digital I/O board to become either one of those. And I'm
not even sure how to get that product to work in what I'm reasonably
sure SIMH could do.

But one problem at a time.

Re: [Simh] Oddball platform as SIMH/pdp11 host

[Gregg Levine]

Hello!
These boards run internally Yocto Pokey (and its descendants) Linux.
However I experimented with an IOT build of Windows on the Gen 1
before confirming that it ran best via Linux. Exposing ports, read
having eight of the digital ones after the serial port, can come
later.

Re: [Simh] DECnet-DOS

[Gregg Levine]

Hello!
It probably would. However I already asked about them. Electronic
copies can be made and sent. Simply because the cost of sending
physical ones across can be prohibitive.

However I'm waiting to see if there is a response from Bit Savers.
Also there might be much the same media for download on their site.

Hello!
Probably a VM, but that's as far as I've gotten. It really depends on
how the software reacts to running inside it. Some of the surviving
examples of software we have available just won't run inside VirtualPC
for example, but will just barely do so inside VMWare.

Re: [Simh] DEC Net for DOS and the product on an emulated PDP-11 OS

[Gregg Levine]

Hello!
What about it? On my system it looks for the tell tales that are found
on the currently popular virtualization flags found on both Intel and
AMD processors, and crashes when it can't find them. It wants me to
find them in the BIOS. I tried to do that eight years ago this
weekend, when the laptop arrived. Not there of course.

VMWare Player is available for free, and will allow you to create
virtual machines without a problem. It's basically the same as
Workstation without the problems of an evaluation period ending and
catching you or the user out. Of course trying to get it to properly
engage on the laptop when running Linux, is a trip to be certain.

Of course I can't go ahead with this idea until I get more feedback
from the rest of the group.

Re: [Simh] OpenBSD on Simh VAX 3.8-1 - Segmentation fault

[Gregg Levine]

Hello!
I agree. Last time I made my big try it was to first have to track
down and build a copy of tcpdump that would build properly on Eleven.
As I recall releases later then 0.8 for libpcap would in fact be
needed for networking to work properly that way. On Linux of course.
On Windows I simply either made use of the Minimal Cygwin project
build files, and of course the tools, and installed beforehand the
Winpcap library. Or install that library, and then a prebuilt binary
who did do networking.

And I am certainly agreeing with you regarding the job they did
concerning the local customization things for Debian and its ilk.

Anyway if this works I'll need to track down the right methods for
shoehorning DecNet onto it. I've other items. The bigger problem is of
course that of remembering which DEC OS the networking stuff ran well
on

Incidentally I've corrected the mispelling of the library name. And my
name is exactly as spelled on the signature. The name you posted must
have been an autocorrect mistake.

Hello!
Okay. That's one for me. And both won and lost. Now about that example
of Pathworks-32, where did you find it? Now my steps are to get a
proper PDP-11 emulation up and running, and of course installing an OS
there, and even picking one... Oh my!

More later I think. But okay.

Re: [Simh] OpenBSD on Simh VAX 3.8-1 - Segmentation fault

[Gregg Levine]

Hello!
Gary which release  of Slackware Linux was this? I've found that SIMH
properly builds on all releases from 7.2 (Which was only released as a
Snap Shot Disk from the time of the first shows) all the way the 14.1.
I only needed to figure out how to update the LibCap library so that
networking would work properly once that arrived not too long ago. As
an aside I moved away from trying to build it here on this laptop
running 14.2 64bit, because networking requires a fixed connection,
not WiFi.

[Simh] Raspbian repository versus Github current

[Gregg Levine]

Hello!
Am I correct in that the version stored somewhere in the Raspbian
repositories is too old to properly grok the idea of using a physical
serial port to talk to a terminal device versus the current Github
one?

I'm planning a project, note the keyword, "planning" in that I'd be
running an appropriate release of UNIX or BSD on the PDP-11 emulated,
and it would need a serial port to talk to a terminal device.

Networking is as it happens optional.

Re: [Simh] Raspbian repository versus Github current

[Gregg Levine]

Hello!
Then the question becomes having the console, that is the simh prompt,
be seen on what's connecting to the Raspberry Pi via SSH startup that
simh/PDP-11 one and after UNIX finishes starting up, the serial port
itself provides the user prompt. How would I set that up?

Re: [Simh] Release of a set of simulators for IBM 7000 series mainframes.

[Gregg Levine]

Hello!
There's already a very capable emulator for the IBM S/360 and IBM
S/370 and possibly the Z900 series members. That is the Hercules-390
one. And it will do practically everything expected, it will run the
VM/370 ones and the DOS/360 also the ones you're thinking of.

In fact at one point it was rated to run the legally available OSes
for the Flexes job faster. (Which demolished the fellow behind it.)

Re: [Simh] Terminal Emulator

[Gregg Levine]

Hello!
Normally I use Putty when it can connect. But Kermit certainly will,
and since it is available for most of what you'd want to run inside,
it will fully enable loading and downloading of files.

[Simh] What happened to IDLE?

[Gregg Levine]

Hello!
I grabbed the sources from GIT earlier today. And promptly built the
two I'll need. PDP11 for one, and the VAX ones for the other on a
Raspberry Pi3. I even added the options for networking that the README
wanted.

So running PDP11 I then saw this happen, and the VAX as well:
pi@raspberrypi:~ $ /home/pi/emul/simh/BIN/pdp11

PDP-11 simulator V4.0-0 Currentgit commit id: 49cfac90
sim> show cpu
CPU 11/73, NOCIS, autoconfiguration enabled, idle disabled
256KB
sim> exit
Goodbye
pi@raspberrypi:~ $ /home/pi/emul/simh/BIN/vax

MicroVAX 3900 simulator V4.0-0 Currentgit commit id: 49cfac90
sim> show cpu
CPU idle disabled, model=VAXServer 3900 (KA655), NOAUTOBOOT
16MB, HALT to SIMH
sim> exit
Goodbye
pi@raspberrypi:~ $

It shows idle disabled. Okay how do I enable it on both? I haven't
decided on a target for them but given that networking on SIMH works
best connected to a fixed source... Anyway I remembered that any
commentary here would need to show those first two lines.

Re: [Simh] What happened to IDLE?

[Gregg Levine]

Hello!
I confess I didn't know that. And given what happens next regarding
the PDP11 one, I shall certainly do all of that, if something does not
work. For option 2 I didn't bother to save the output shown when
making it, so I'll do that again, and save it to a text file.

For SHOW VERSION, shouldn't it be the same as what's shown in my selection?

Re: [Simh] hp alternatives

I agree.. Once again HP  is doing something revolting by exiting a
valuable arena, by ending VMS for hobbyists, this is indeed something
for those of us who do, to look into.

Re: [Simh] Is it possible to simulate the first Vaxen I ever used?

[Gregg Levine]

Hello!
I agree with you Tim, that's an excellent book on the subject.
The AM2901 was used in some DEC designs that I know of. In fact in the
databook I have here, AMD mentions that some part numbers were
themselves designed for those DEC designs. And that some LSI-11
designs found themselves fully built using the AM2901. The sequencing
parts that the company made were in all probability not used inside
them. But were used elsewhere.

Oh and some of the DEC designs did also use the Series 74 ALU ,the
SN74181 one. I remember that from some reading about the entire design
process. In fact that TI ALU is itself a complex part, perhaps almost
as complex as the 74S481 that Mentec would attempt to use many years
later.

Re: [Simh] Lost PDP-11 OSes?

[Gregg Levine]

Hello!
Take a look at the list of PDP-11 OS examples on the Wikipedia site.
Of those I think I recognize most of them. This includes the ones
discussed here. For myself I'd like to track down the last known
working release of the R named operating systems for the PDP-11. Up to
the user to pick one.

Re: [Simh] Printing to a pdf

[Gregg Levine]

Hello!
CUPS, the regular printer management widget on most Linux systems
supports the logic behind the print-to-pdf functions that the
correspondent wants. There's even software out there that helps CUPS
do that. But it depends upon which Linux distribution the
correspondent is running.
