I have created images of DEC ODS-?3 CD's to overcome the SIMH/w98
foreign mounting problem, which I don't gather isn't your problem.  I use
Adaptec EasyCD for this.  Commercial.  Oddly this will still work if you 
write the image back onto a CD-R encapsulated in the native filesystem.
SIMH/Linux isn't supposed to require doing this stupid thing.
