Every(?) VAX has a special serial port (on some Q-BUS VAXen I've seen it's located directly on the CPU board). This is the operator's console, the serial line the VAX' BIOS communicates with. Under VMS the device is called OPA0. The situation can be a bit different if the VAX has a graphics card built in (i.e. is a "workstation" class VAX). On those there's a DIP switch that controls where the BIOS output is directed to - the special serial line or the graphics card. cu, Martin ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
Re: [Simh] Console floppy and VAX 780
I'm not sure I understand the question. Get what working? Do you have a real 11/780? Because the simh VAX-11/780 do not use the floppies, as it don't actually emulate the PDP-11 that is used in the FE.

Re: [Simh] vax simh and loading file
Wilm, Your suggestion on the simh list looks just like what I need. I use simh 3.9 and the vax has a cr device. I attached a file and everything is good. When I login to vms nothing understands job. I've tried job @sys$system:job and so on and can't get job or find it anywhere. The help list doesn't list a noprint qualifier but there is /keep and /name. Where is "job" that's what I can't seem to find out. This is from the list.

[Simh] Tell me about console terminals and related things
Hi All, So as I delve into VMS and related concepts, I’ve come across mention of console terminals and “operator’s consoles.” I gather that SIMH simulates one of these when the machine starts up, but I’m a bit less clear on how this compares to the real hardware. When the VAX boots, it obviously has a prompt for boot options and such. Would this be displayed on, say, a VT100 somewhere? I gather SIMH itself doesn’t do much terminal emulation, so it might be worthwhile sending the console output to another emulator which could handle the keyboard and such. I guess this depends quite a bit on the OS and machine in question too. :) ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh

A VT100, or more commonly a printing terminal, so that you have a paper trail of what was written preserved for later.

I guess this depends quite a bit on the OS and machine in question too. :) You always do. What do you think that window in which you are running simh is? It's a terminal emulator. Or are you running simh from a serial line? In which case, you must already be using a real terminal, or how did you otherwise start simh?

This is from the list. >" So this is your "card" file? $JOB SYSTEM /NOPRINT /KEEP /NAME=WilmTest $PASSWORD xxx $! some ASCII text $ show time $EOJ" That should work fine, and here's what would happen on a real VAX: 1. User loads card deck into card reader and hits the start button. 2. VMS reads each card in turn and creates a temporary file somewhere (my guess is that it would be in the login directory for the user specified in the JOB statement on the first card). 3. VMS submits the file to the batch queue specified by the /QUEUE qualifier on the JOB statement, or to SYS$BATCH if the /QUEUE has not been specified. 4. The job runs and creates log file, which will be printed and/or deleted unless other qualifiers on the JOB statement specify otherwise. To summarise: card readers create batch jobs which run without the user having to log in via an interactive terminal. The JOB command itself is not actually a valid VMS command in the usual way: it's not part of DCLTABLES.EXE and is instead implemented (I think) by the VMS JOB_CONTROL process.
