I have seen the VMS technical Journal article about adding physical CD support to SIMH. My version of SIMH (the latest - 3.8-1) does not seem to support this and I can't find it on the Migration Specialities site either.
Is this possible? How?

Nothing in the change log about such a feature either. |

Haven't read that article so not sure if this is what you want. But when running SimH on Mac OS X (i guess Linux will behave the same) just add the path to your CD drive in your configuration file.
e.g.
attach -r rq3 /dev/disk2s0

Tried that with Ubuntu Linux and it did not work. SimH wants a file or partition.
I was able to use unformatted partitions on virtual disks created by Virtual box which Ubuntu was running under.
I got access to the Mac's CD-ROM by running FreeAXP in another Virtual Box VM and clustering the two systems. Through MSCP this works. |

I'm starting SimH sudo'ed.
Were you running it as root as well? |

I am running SimH Sudo'ed. It is in on a Linux VM that is mostly dedicated to it. |

I'm running it under my regular Mac OS system. Ok, never mind, it was just a thought...
I looked up my folder with the docs.
"SIMH FAQ 07-Sep-2005" on page 7 it says:
2.5 How do I transcribe a real CD for use with SIMH?
- On UNIX, you can copy a CD to an ISO file with the dd command:
% dd /if=/dev/raw_cd_device /out=/path/cdimage.iso
- Linux, and many Unix variants, support direct access to the CD ROM from SIMH:
sim> set rq1 cdrom
sim> att rq1 /dev/cdrom_drive
So i've forgotten to mention the "set" command. sorry!
But as said, it's working here:
In my vax.ini:
set rq3 rrd40
attach -r rq3 /dev/disk3s0
On the console:
sim> sh rq3
RQ3, 681MB, attached to /dev/disk3s0, read only, read only, RRD40 |

I just tried that and it worked this time.
I think I specified the mount point before instead of the device link.
So now I can use the virtual box cdrom manager to change which cd-rom image or even the physical cd-rom. |
