Tony's point is very well taken, and you seem to have missed it, and
substituted something else that Tony did not even imply.
First of all, a pure DOS computer is a VERY handy tool to have around. At
least it is for me. There's a lot you can do with a simple DOS box and
some good tools (like ProComm for example).
But to use Teledisk as the de facto standard for archiving floppy disks
would be an awful mistake, not the least of which is because Teledisk, as
Tony rightly pointed out, does not deal at all with GCR disk formats.
Any format that is going to be adopted as the de facto standard for
archiving disks (and other media) must be able to handle ANY format, and
must also be OPEN, DOCUMENTED, and most importantly, NON-PROPRIETARY.
I think this is pretty much what Tony said.
