I think this is an appropriate question for software.... Id gotten a large collection of 5.25 floppy disks from a coworker of mine, who had used some of them with an Apple 2 at the time he was in Army. Since I dont have an Apple 2 anything currently, I was curious if they could even be viewed in DOS? Just a simple pop in and "dir /w" thing. I was also given a 5.25" drive cleaning kit, complete with the card, bottles of various cleaning stuff, the cleaning floppy, etc. same deal, i wonder if I could use it with a DOS machine or Win95 machine.

Edit: He mentioned that some IBM systems would be able to read the Apple 2 disks last he knew. So maybe some version of IBM's PC-DOS can?

Hi I don't know for sure. But there is a chance that DOS programs (utilities) exist that can read them (Teledisk etc).

Back in the 90s, for example, I had found such a utility on a shareware CD.
It allowed me to read Apple Macintosh diskettes.

Same goes for CP/M diskettes, I guess.
Some of the CP/M emulators had utilities with them to read real CP/M diskettes on your PC.

Even if it's not directly possible, then there might be hacks to read such disks.

For example, the Amiga had a floppy drive controller with variable speed..
That made Amiga diskettes hard to read onna PC, which had a -more or less- fixed-speed floppy controller.

However, by using two diskette drives and a blank floppy
(or by using one diskette drive and a wire going from it to parallel port),
it was possible to read an Amiga diskette on DOS.

So I think it might be possible to read Apple II disks on PC.
Just not without an utility. MS-DOS and Apple DOS use different file systems.

Edit: Encoding is also different - MFM vs GCR, but that doesn't really matter anymore when it comes to hacky solutions. 😉

Edit: A good start would be Omniflop/OmniDisk, normally. However, it doesn't mention Apple II.. 🙁

Things might have changed since the last time I checked and I am surely not up-to-date on potentialhacky solutions, but, AFAIK, reading GCR disks in a IBM PC or clone is not normally possible due to the limitations of the IBM standard floppy disk controller (and clones thereof) design . If there exist new-ish hacky workarounds, especially if they requires little or no extra hardware or mods, I would like to know about them .

Some options (including hard to find ones), off the top of my head (with a little help from Google for URLs) :

The machine im likely to use for this is my new windows 98se build (still in the mail rn) so ill probably see if the utilities would work in dos mode there when i get the system together.
