AOL did delete everything quite unexpectedly... if you ever find that stack on a floppy or elsewhere, email me ([email protected]) and I'd be happy to assist getting it running online.
We hope to keep the upload website running for a while, so if you do stumble across your stacks in a few months, you should still be able to get them running on the Archive.
Also, every stack in the Internet Archive has a downloadable disk image that can be downloaded and run offline in an emulator, or on an old Mac if you still have one.
If the XCMD comes with a sample stack, that stack will be uploaded. If it's just an XCMD it may be trickier. If you find any stack that isn't working because of a missing XCMD (or any other reason) then let me know - [email protected]
