[Simh] need help with vax780 on linux

[Dan Gahlinger]

Incorrect, if it was booting the CD, the banner would show VMS 6.0
not VMS 4.2, so it's definitely reading the DSK

    Just some thoughts that fly by in reading you post:

    From the mailed .INI-file, the commands set up rq0 as a CD with an
    attached .ISO-file.

    Then you try to boot from this "CD".

    

    Q1: Should the 780-emulator be able to recognize a CD as a device? -
    In those days the TU58 was "the media" for console works...

    Q2: If this booting is proper after all, and the file you have
    attached to the rq0 is the boot-disc you intend to use, should it
    really be attached to a "read-only" device like a CD, not to a disc?
    - I know later systems can boot from a CD, but doesn't that require
    booting a system image that is tailored to this task - i.e. that
    doesn't require any dump-files or similar?

    

    (You say that the emulator reads your .DSK properly, but to my eyes
    does it only read the file vms6_0.iso, ie the CD-immage).

    

    All my best anyhow - every effort to maintain this generation of
    systems indicates a great spirit!
