Thank you, this is rather unexpected. On Sat, Jun 29, 2013 at 4:02 AM, Jordi Guillaumes i Pons <jg at jordi.guillaumes.name> wrote: This could be of general interest for the list members.

El 29/06/2013, a les 5:01, Bob Armstrong <bob at jfcl.com> va escriure: SIMH DMC-11 emulation is good ... Is that available yet? It does, in the development version of simh. I have observed some issues (the performance goes down when there is more than a DMC device active). There is also the asynchronous alternative (DDCMP over DZ device).

Multinet (over UDP) is such a fundamentally broken idea that it would be a *really* good idea to get rid of it. Every other option is vastly superior. GRE is a good one because it emulates a datagram datalink (Ethernet) over a datagram transport (IP). SIMH DMC-11 emulation is good because it emulation a connection oriented datalink (DDCMP) over a connection transport (TCP). Conversely, Multinet runs a connectionless transport to carry DECnet point to point traffic, in gross violation of most of the datalink requirements. So it only just barely works part of the time, and it can't possibly ever work any better. paul

SIMH idle

Hello! Mark, I've built SIMH (again) and had the rig record the build functions via script.

Just last night I got code pieces from Matt Burke (the guy at 9track.net) to add VCB01 (QVSS) support to the simh codebase for the MicroVAX I and MicroVAX II simulators. I'm in the process of merging that code and adding the necessary build mechanisms to the makefile as we speak. This will be cleaned up and visible at https://github.com/simh/simh in at most a couple of days.... For folks who build their own binaries, the latest github code has a VAXStation I and VAXStation II with the MonoChrome QVSS video capabilities. sim> SET CPU MODEL=VAXSTATION enables the video subsystem. The VAXStation I has a limit of 4MB of RAM, the VAXStation II has a limit of 16MB. The makefile should just build the right thing if the development support for libSDL is installed on your platform. Please provide bug reports and/or other feedback with issues created at https://github.com/simh/simh/issues There is a glitch in my scripts which build and package the windows binaries which is failing to build the simulators with video support, so folks who count on the Windows Binaries will have to wait until I fix this. The Windows Binaries (including VAXStation I and VAXStation II) are now available at: https://github.com/simh/Win32-Development-Binaries Download the latest zip file. Hello! Nice to know Mark. Any suggestions for implementing it on a Raspberry Pi system w/ 512MB of memory? I don't see any reason it wouldn't work as long as you've got the right SDL development pieces available. I did get the code outside of your screen idea to build properly. I'm not sure what this sentence means.... what does "code outside of your screen idea" mean? - Mark Hello! Oh sorry. I meant everything contained within the entire SIMH retrieval except for the screen presentation method. I think you are trying to say that all simulators except the MicroVAX I (VAXStation I) and MicroVAX II (VAXStation II) built. OK, that is expected. Numerous folks are running the latest code on Raspberry Pi systems. The QVSS video on the MicroVAX I and MicroVAX II simulators was just merged into the code base last week. If you can't get the MicroVAX I and MicroVAX II to build, I'm going to need more information to help. Please create an issue at https://github.com/simh/simh/issues to record the problem and to contain the details of chasing this down to a solution. Please Include the output produced when you attempted to build these simulators. Thanks. - Mark Hello! That's just it Mark. After using the git pull <repository name> command to pull everything into the source directory I chose, I then entered the created one, examined everything briefly, and then entered the command make and off it went. I first made the BIN directory, and then did that. I did need to build the Altair ones out of sequence however. Also the Nova one as well. I did not make the ones for the older IBM machines or the other simulators that I wasn't familiar with. I found that the screen thing needed the SDL library and I wasn't ready to massage the repositories that make up Debian on Raspberry Pi to find that one so I let wait. My only complaint is that when I ran the vax simulation to confirm that was all working, it then told me that the IDLE function was disabled, that was when I asked it about the devices. Hi Gregg, Nothing in the new codebase should have changed idle behavior (or availability) for any simulator. Please provide the output of "SHOW VERSION" in the simulator which isn't behaving as you want. The complete output produced when the simulator was built will also be useful. - Mark Hello! Coming up soon Mark. Several days ago I reconfigured my Raspberry Pi to reflect using the most recent and updated release of Debian on the thing, and containing the materials for our concerns. (That meant I ran the regular tools for Debian to update things on it.) And as it happens I also earlier did a fresh pull from your Git repository and built everything fresh. Then the system told me that it was as I related earlier. I'm not sure if the mail list can support attachments so when I get everything ready I'll create a new thread and provide details as to where everything is available. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."
