BTW, This discussion is Section 2.5 of the SIMH FAQ. Read it and weep.

> Don't look for the ISO keyword, which is usually associated with

> The VAX Hobbyist CD has a single track for VMS that can be read 
> and saved to a file, which is the Windows equivilent of 'dd'.
> If you name the save file extension '.iso' that's up to you;
> it has no intrinsic meaning, and does not change the format of the

> Roxio has had this feature since around version 4. It depends on

> ----- CAUTION -----
> I was unable to correctly read my VAX Hobbyist CD
> at a high rate of speed. Ripping the track slowly at 4X gave me a good
> copy.
> Ripping it at 24X+ gave me a corrupt file, which exhibited 'strange'
> symptoms like the one you describe with the 'unknown 
> processor' message.
> Since you will only need to do this once, try slowing down your rip.
> This may be a quality issue with the Hobbyist CD 
> manufacturing process.
