Hello,

I've found a couple of problems:

• dpni20 complains about not being able to lock shared memory
• dpni20 is not able to locate the vde control directory

System restarting, wait...

The boot sequence continues but the simulator hangs and it has to be killed.

/tmp/vde exists and it is under vde control:

MacJordi:~ jguillaumes$ ls -ld /tmp/vde

The dpni20 program is set said:

And this are the contents of my INI file:

; Ready to GO

It would be nice to run the 8080 software.

For practical use, KLH10's front end is very convenient with its ability to load programs directly from the host file system. But this leaves a gap when it comes to running ALL THE SOFTWARE.

I tried building base-ks-its on Ubuntu 14.04 LTS and ran into build issues, and after fixing the easy one preventing kn10-ks from building, could not bring up ITS.

The compilation issue is a reference to asm/io.h in dvlites.c. This was easily fixed by changing "asm" to "sys". This fix allows kn10-ks to build. Another issue prevented dpimp from building having to do with "struct ifreq" not having a member named "ifr_space".

But most importantly, ignoring the failed dpimp build, and trying to run ITS with "kn10-its klh10-md.ini", KLH10 makes it through the ".ini" file, but when I try to start (by typing "GO"), I get the following error:

KLH10# go

I have attempted several times over the last few years to build klh10 on modern versions of macOS, generally trying to follow the information on the network about converting makefiles to Xcode projects (and failing miserably).

How in fact do people build klh10 on macOS?

I am running ITS from this repo https://github.com/PDP-10/its
My home network is 192.168.0.0/24
I have built and installed on a Raspberry Pi 4 with wired Ethernet, Static IP 192.168.1.223. I also reserve 192.168.1.45 on the router to make sure it does not get handed out by DHCP.
When I SSH into the Pi I cannot Ping or FTP to 192.168.1.100 or ping 192.168.0.45 once ITS is running.

Is there any other step I am missing?
I also tried setting the gateway to .223 but that did not work either.

Any help would be appreciated

SIMH has the ability to boot from a tape. I would like that feature in KLH10 too.

(Why? Because I'm working on an automated ITS installation, which starts from boot tapes.)

There are three KLH10 copies at GitHub. I suggest merging them all into one.

I tried to contact KLH but got no reply, so I guess we're on our own.

The instructions and Makefile seem fuzzy on the notion of having all three emulators: kl, ks, and ks-its installed at the same time. In doc/install.txt, I read that I should do make -C bld-<model> install. But for each successive run of that for a different model, the previous install gets thrown into $KLH10_HOME/flushed. The instructions aren't clear how that directory is used. It seems that it be easier if we could install the assorted binaries to $KLH10_HOME/<model>/.

Am I missing something really obvious here?

I'm experimenting with running ITS on KLH10's KL10 model B.

The branch is here:
https://github.com/PDP-10/klh10/commits/lars/kl10b-its

Towards the end of building the bld-ks-its target, I get this warning:

../../src/dpimp.c: In function âarp_reqâ:
../../src/dpimp.c:1210:2: warning: âmemcpyâ reading 6 bytes from a region of size 4 [-Wstringop-overflow=]
  memcpy((char *)arp.arp.arp_spa,  /* Sender IP addr */
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   (char *)&ihost_ip, sizeof(arp.arp.arp_sha));
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gcc  -o dpimp dpimp.o dpsup.o  

If you e.g. do "make base-ks-its", it would suffice to create kn10-ks-its once, but the Makefile created by mk/bld.mk repeats the "make base-ks-its" in all subdirectories, i.e. in bld-kl, bld-ks, and in bld-ks-its.

It would seem more reasonable to only do "make base-kl" in bld-kl, "make base-ks" in bld-ks, and "make base-ks-its" in bld-ks-its. Saves time, at least.

Hello,

This report should be confirmed by someone else.

Apparently, commit ba556fb has introduced unstability to the KL10 emulator. Now TOPS-20 freezes a few minutes after boot up. It also freezes almost immediately if a CHECKD is requested on boot.

I've tested it with the PANDA distribution. Going back to 9d13c2b seems to "fix" the problem.

Possible diagnose: the increment in the number of devices causes a memory overwrite somewhere. I have not looked at the code yet.

KLH10 doesn't have an ethernet card for the KS10.

There is half-finished support in ITS for using an NI1010. @atsampson is working on adding support for a DEUNA card.

Consider this compiler warning, which I deliberately did not fix:

cc -c  -g3 -O3   -I../src -I../../src  -DKLH10_CPU_KS=1 -DKLH10_SYS_ITS=1 -DKLH10_EVHS_INT=1 -DKLH10_DEV_DPTM03=1 -DKLH10_DEV_DPRPXX=1 -DKLH10_DEV_DPIMP=1 -DKLH10_SIMP=0 -DKLH10_MEM_SHARED=1 -DKLH10_RTIME_OSGET=1 -DKLH10_ITIME_INTRP=1 -DKLH10_QTIME_OSVIRT=1 -DKLH10_IMPIO_INT=1 -DKLH10_CTYIO_INT=1 -DKLH10_APRID_SERIALNO=4097 -DKLH10_CLIENT=\"MyITS\" -DVMTAPE_ITSDUMP=1 -DKLH10_I_CIRC=1  ../../src/klh10.c

I would say that the compiler is running in the wrong locale for this particular program: klh10, or rather the operating systems that run in it, doesn't know what to do with utf-8 text and/or terminals.

We can probably fix the locale of the compilation run, but how can we make sure that the user runs klh10 in a proper ASCII or ISO-8859-1 terminal?

There seems to be some problem reading from tapes. This is an extract from my configuration file (based on run/ksits/klh10-pi.ini):

devdef mta0 rh1.0 tm02 fmtr=tm03 type=tu45
devmo mta0 minsys.tape
load @.nsalv-260-u
go

minsys.tape is a tape image created with itstar. It works fine with SIMH. @.nsalv-260-u is the ITS disk salvager from run/ksits.

When I type go and then mark<ESC>g, the disk formatting procedure works ok. (Answer 0, y, 0, n, 3000, foobar.)

But next, if I type tran<ESC>g to restore files from a tape, things sometimes go badly. (Answer 0, y.)

On some of my host machines, the start of a file is found, but then I get

Tape offline or controller not ready
*** ERROR *** THE SYSTEM MAY NOT BE BROUGHT UP

On some other host machines, sometimes all files are restored, or the error appears in the middle of the tape.

If we look into the source code of NSALV 260, we see

MREAD2: MOVEI B,<%TMD16_8.>+<%TMFCD_4.>+TMBTS
        IOWRI B,%TMTC           ;Tell TM03
        MOVEI B,%TMNOP          ;You may need this to set status values
        IOWRI B,%TMCS1          ; but I'm not really sure

         TRNN B,%TMSFR          ;Formatter ready?
          LOSE "~&Tape offline or controller not ready"

• %TMTC is the tape control register at 772432.
• %TMCS1 is control and status 1 at 772400.
• %TMFS is formatter status at 772412.

So presumably, the tape controller is ready, but the tape formatter is not.

On a NetBSD system to which I have access, the autogen.sh script hangs in aclocal (repeatable running aclocal interactively) with a prompt "root#"

Has anyone built klh10 under NetBSD before?

The PDP-10 (specifically the KA-10) was the first computer I ever used and my first job was as a TOPS-20 assembly language programmer, so I wanted to play around. I am on a UBUNTU linux system. After some bumbling around I got it built and it 'starts' ok

TOPS-20 tapes store author information, read20 should print it.

For dump.h add:

#define WdoffAuthor      WdoffFDB+030   /* Author offset */

Then in doFileHeader:

    getstring(block, authorname, WdoffAuthor, sizeof(authorname), STRING);

and print it when in verbose mode:

printf("%5d%9d %2d %o %s %s %s", offline ? apgcount : pgcount,
                   numbytes, bytesize, tprot, timeptr, topsname, authorname);

The code to default the serial numbers of massbus devices seems wrong.

dvrpxx.c:

 RPREG(rp, RHR_SN) =                /* Serial Number register (BCD) */
               (((1    / 1000)%10) << 12)
             | (((6    /  100)%10) <<  8)
             | (((nrps /   10)%10) <<  4)
             | (((nrps       )%10)      );

dvtm03.c:

 TMREG(tm, RHR_SN) =                /* Serial Number register (BCD) */
               (((9    / 1000)%10) << 12)
             | (((9    /  100)%10) <<  8)
             | (((ntms /   10)%10) <<  4)
             | (((ntms       )%10)      );

The intention seems to be to set the serial number to 1600 + n and 9900 + n
respectively. It does not...

It would be useful to add SLIRP as a networking option.
Currently I get very annoyed that the Panda install on my laptop only has working networking when it is in the correct location.

contrib/supdup doesn't compile on modern Unix. I've started to modernize it so that it compiles, but it is not finished yet. Hopefully it is going to work with ITS after that.

I've built kn10-kl on the latest Stretch version of Raspbian (2018-3-13) for a Raspberry Pi 2. It works perfectly running TOPS-20 but when I try to boot TOPS-10 I get the following error loading the boot loader:

The Chaosnet UDP tunnel listens to all interfaces, including the tun interface used by the IMP.

I used a firewall rule to forward all Chaosnet UDP packets from the host to the ITS IP number. Then @b4 asked if this was necessary, and that got me thinking that it shouldn't be. But it was, and it worked. When I removed the rule, it still worked.

So I looked in the code, and there it was: dpchudp.c binds to INADDR_ANY.

Maybe chudp should accept a parameter, say if, and bind only to those interfaces.

I'm about to migrate my oldest TOPS-20 system from klh-2.0h (last touched 2012) to this version, and discovered that NI20 tap interfaces don't work as they used to. It seems there is a little bit of confusion about the usefulness of tap-only devices (as opposed to tap+bridge devices), given comments in the code.

In my experience, tap-only devices are very useful as tunnel devices if they have their IP addresses set up (as they were in 2.0h). I just committed 510aedc which changes the crucial test to whether (in effect) the tunaddr parameter was given (indicating that it is to be used as a tunnel device) rather than checking pfdata->pf_ip4_only (indicating a tun (rather than tap) device).

I'm not sure if the other places in the code where tap+bridge is mentioned also need looking at.

And I think OSN_USE_IPONLY should be abolished in favor of pfdata.pf_ip4_only, but that's another matter.

(Sorry if this looks more like a rant than an issue.)

@Pul-Ess discovered that KLH10 will crash if the host machine is out of memory and allocation of a shared memory segment fails.

Specifically, inside dvrpxx.c rp_clear will fail if rp->rp_sdprp is NULL.

klh10 absolutely eats every sysvshm resource I have on my FreeBSD system - and them for some reason I can't ipcrm them, despite it saying it succeeded.

No particularly helpful errors are returned indicating it is shm-related, either.

I have an issue building kn10-kl on High Sierra: A number of places have an interrupted format string in a write to a log file, and the compiler complains about a missing ")" at the end of the first part of the string. I will freely admit that I am using the original Panda distribution, which build just fine in 2011 on whatever generation of OS X that was, but the binaries will not run under High Sierra so I have to rebuild.

Has this been fixed in the Github variant? Or is there a known fix which I am missing?

This was easier when I had numerous Linux and BSD systems lying around the museum; now I'm stuck with my home resources

Secondarily, has anyone created an Xcode project to build KLH10 natively on the Mac?

Thanks,
Rich

Any plans to implement VDE support? (vde2, http://sourceforge.net/projects/vde/files/vde2/) It would greatly simply my running of VMs on BSD. ;)

Has anyone tested KLH10 on an Apple M1 machine?

It seems the console device can get into trouble if it receives input too fast. Error messages typically look like:

[CTYI: 153 => 553, old 465]

Sorry I don't have more details right now, but I can probably cook up a test case.

Implement a printer device that just pipes everything to lpd and friends so I can print to my networked SIXEL dot matrix printer from ITS et al.

I decided to feed the source (well, the ITS build, for the moment) through the scan-build utility, and it did indeed turn up a bunch of issues, some of which are trivial patches (e.g. unused or uninitialized variables), others (use-after-frees, for example) that are probably best subject to the gaze of someone who has actually spent time with the code, and in any event I don't want to step on anyone's toes. Would it be best just to attach the results for people to pick over?

tap0 is up and connected to the bridge -

[root@wol ~]# brctl show
bridge name	bridge id		STP enabled	interfaces
docker0		8000.0242d6e8cae6	no

virbr0		8000.000000000000	yes		

But no IP address on tap0 -

[root@wol ~]# ip addr show dev tap0

       valid_lft forever preferred_lft forever

If I manually add an IP address -

[root@wol ~]# ip addr add 192.168.0.51/24 dev tap0
[root@wol ~]# ip addr show dev tap0

I can ping it, but not telnet to my Panda -

Entire network broken -
At this stage, the networking on my machine is broken, I can ping my own interface (192.168.0.5) and the tap0 interface (192.168.0.51) but nothing's going into or out of my machine. Once I shutdown klh10, everything's back to normal.

Closedown works
On the plus side - dpni20 no longer hangs around, and everything shuts down properly.

If you need any more info/debugging, please shout.

Make it possible to mount a tape image R/W, or change from R/O to R/W.

Is there already a way? If so, I haven't found it.

Just putting out a feeler. Would anyone be interested in adding support for the KA10 processor and devices? There is some vestigial code for it here and there.
