For whatever reason, I have an 8" floppy disk with one of these microwave cookbooks on it. Mine seems to be (part of?) one called "The Guaranteed Goof-Proof Microwave Cookbook" by Margie "Microwhiz" Kreschollek.

Sadly, I've never been able to read the book in the correct order as I don't know what system it came from - it's something that is single-sided, 77 tracks, FM (single density) encoded with 26 sectors/track, but the text is there in a hex editor.

It makes it pretty obvious that it isn't a joke or trick; someone saw it fit to fill up a 250kB disk with this, so somebody must have thought it was a good idea.

In an unrelated endeavour, my dad told me he once tried to cook an entire turkey in one of those huge 80's microwaves. He said it didn't turn out very good.
