I found one of those at a tag sale for $0.25 years ago (felt awesome handing over the quarter for the bag, lol). In the main compartment, it can fit a PowerBook 165 and a GCC WriteMove II -perfectly-. Its AC brick fits very nicely in one of the side containers.

I later learned it was for a Apple IIc, and wanted one ever since I found that out. By the time I actually got the IIc, though, the case was long gone. I don't remember what I did with it.
