From: "Rob Jarratt" <robert.jarratt at ntlworld.com> If you want to peer with me using DMC11 let me know. I will need to know your IP/DNS address and a port you want to listen on. You can download a Windows executable of the VAX780 emulation with DMC11 support here: http://sdrv.ms/Lmg33s I am hoping that the DMC11 will be in the next release of SIMH, and perhaps in the PDP11 emulation too. To configure your side you need the following commands: So, does the DMC11 emulation just send DDCMP messages in UDP datagrams, or is it more complicated than that? I've been meaning to add DMC/DMR emulation to Ersatz-11 for centuries, and obviously I'd want to make sure it interoperates with SIMH. (There are already undocumented ASSIGN/DEASSIGN/SET/SHOW XM: commands since ages ago, but the resulting device doesn't actually work.) Thanks, John Wilson D Bit

VCF-East on HECnet?

by hoelscher-kirchbrak＠freenet.de

Hi, to all who are interested in trying the new DMC11 network device within the simh prototype (available from Rob, see his mail), here is a short instruction how to configure it under DECnet/VAX: DECnet/VAX Setup for DMC11s If you haven't set up DECnet using netconfig.com yet, so do it now. The netconfig.com command procedure will recognize and set up your DMC11(s) automatically. Otherwise (DECnet already configured, e.g for Ethernet), do: $! ================================================================== $! Setup for two DMC11s, DMC-0 and DMC-1 $! ================================================================== $ RUN SYS$SYSTEM:NCP SET EXECUTOR STATE SHUT DEFINE LINE DMC-0 STATE ON DEFINE CIRCUIT DMC-0 STATE ON COST 5 DEFINE LINE DMC-1 STATE ON DEFINE CIRCUIT DMC-1 STATE ON COST 5 $! $ @SYS$SYSTEM:STARTNET $! That's all! When everything's o.k. (including your network partner's DMC11) the following command should show the line state "on" a while after DECnet has been started: $ MC NCP SHOW KNOWN LINES Known Line Volatile Summary as of 4-NOV-2012 11:22:33 Line State DMC-0 on NCP> More or less unwanted states: DMC-0 on -starting means: still trying to connect to the other side ..., should be gone after a maximum of 30 seconds, otherwise there is a problem DMC-0 on -synchronizing shows up when the other side has been connected, but is not synchronized yet, usually doesn't last longer than a second or two To get rid of one or more DMC11s, just do: $! ================================================================== $! Removal of e.g. second DMC11 DMC-1 $! ================================================================== $ RUN SYS$SYSTEM:NCP SET CIRCUIT DMC-1 STATE OFF PURGE CIRCUIT DMC-1 ALL CLEAR CIRCUIT DMC-1 ALL SET LINE DMC-1 STATE OFF PURGE LINE DMC-1 ALL CLEAR LINE DMC-1 ALL $! Hope this helps - if not, ask for more! Regards, Ulli --- Alle Postf cher an einem Ort. Jetzt wechseln und E-Mail-Adresse mitnehmen! http://email.freenet.de/produkte/basic/index.html

I'd be interested in trying that. The Unibus emulation should just carry over. Is the source available? paul

3w3 to 3x BNC Cable

There are some VGA-->BNC cables on ebay, I got one last week for 6. You could cut the vga connector off and solder to a 3w3 plug. You should be able to get one through RS or Farnell cheaply The issue is thus: I(t's a DEC cable with a moulded 3w3 plug and the cable has pulled at the 3w3 end, I suspect the wire has snapped inside the 3w3 plug. I'm getting another cable to prove the VAX is okay first and when I have that working I'll do some surgery on my existing one. I'de make one up using existing stuff I have if I had any idea where to get 3w3 plugs from, they seem to be like rocking horse doo-doo. -- Mark Benson http://DECtec.info Twitter: @DECtecInfo HECnet: STAR69::MARK Online Resource & Mailing List for DEC Enthusiasts.

It appears after a multimeter test that the green wire in mine has broken, the cable insulation has split behind the 3w3 connector so I think the cable has been pulled on and broken. Make that two. I'm also on the hunt for one. :-) Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B. Idol

Thanks, Mark - there is currently one on eBay unless it's been snapped up. I can see 3 - all in the USA. -- Mark Benson http://DECtec.info Twitter: @DECtecInfo HECnet: STAR69::MARK Online Resource & Mailing List for DEC Enthusiasts.
