I have some 8 inch disks that were created on a PDP11/70 running rsx11m, and need to transfer them to a PC. The problem is I do not have access to the DEC anymore. Supposedly the information is in a generic text format, but I can't read the disk format with my current hardware. If anyone can do this transfer, or provide information on how I can perform it myself, please contact me directly at: Jay Brown 2434 Main Street # 201 Santa Monica, Calif. 90405 (213) 399-7733 uunet!bambam!luke

Your data may be stored that way but it will very difficult to extract it without a thorough knowledge of the Files-11 on-disk structure. Files-11 builds non-contiguous files and you have to use the file directory to locate all the needed pointers and sizes. If you don't have your DEC machine or the manuals, you would be best advised to contact an RSX expert. I used to be one, but I also have moved to a non-DEC world (SUNs and standalone 68020's) or I try to help. Try posting your request to the comp.sys.dec newsgroup.

If you have access to a VAX780 or a VAX785 (running VMS) you should be able to read it. Both of these machines are booted by a LSI-11 that has an eight inch floppy disk on it. You will need physical access to the machine as the floppy is only reachable once the front doors are open. The LSI-11 runs RT-11, but if you 'mount' the floppy you have access to it from VMS. Mounting the floppy requires that a CONNECT CONSOLE is done some where in the system startup or by someone with the right privs. Once this has been done then the floppy is available as CSA1: You can then run the EXCHANGE program to dir directories, copy files to and from the floppy, etc. -- john R.
