Subject: non-PC Floppy imaging
Hi,
I now have a number of uCode diskettes for my IBM 4331. I would somehow
like to image them so:
a) I have backups in case the floppies themselves go bad
b) be able to investigate their contents in case I have to ?merge? the
contents of multiple floppies to
make a single good one
These are all 8? diskettes.
The complicating factors in all of this are:
a) any text (e.g. strings) are going to be in EBCDIC rather than ASCII
b) each uCode diskette was presumably serialized to the CPU it was for
c) not sure what the ?on-disk? structure looks like
d) the only 8? diskette drives that I have are in IBM (non-PC) equipment
Any ideas/comments would be welcome.
IBM invented the 8" floppy disk format. Generally their disks follow the standard
3740 format. I would try that first.
