Jerome Fine replies:
Are you saying the actual CD image was available as

I have the RT-11 CD sent from Tim Shoppa, so I am
satisfied it is OK. BUT, I also want to burn my own
CD in the same manner. ALSO using Windows 98 (Yeck).
If anyone wants a copy, please ask!
The RT-11 Freeware CD is composed of somewhat less
than 212,992 sectors (of 2048 bytes each) which contain
about 403 MBytes (Windows 98 Explorer says 21,223 files
in 969 Directories using a total of 403,733,960 bytes)
all contained under (if I have been told correctly) the ISO
file structure for a CD.
Starting at sector 212,992 on the CD, there are 114,688
sectors which hold 7 RT-11 partitions of 33,554,432 bytes
each for a total of 234,881,024 bytes. These sectors
can be accessed only by software which understands
the RT-11 file structure, in particular programs such
as PUTR, VMS Exchange and of course RT-11 itself.
I can duplicate the above combination.
I can copy files to a CD into an ISO file structure.
I can also copy a file on the hard disk (which contains
RT-11 files under the RT-11 file structure) to either a CD-R
or a CD-RW starting at sector zero.
BUT, Can anyone help me? I want to copy that same file
to a CD-R or a CD-RW starting at sector 212,992 (just
like Tim Shoppa did) after I have written the files to the CD
under the ISO file structure. Of course, I want to be able
to do this under Windows 98!! Does anyone know if that is
even possible, let alone how it could be done?
Sincerely yours,
Jerome Fine
