Ah hey, and why not post these too, while I'm in the process of installing one of them on the new G4 hotness? Here's my little collection of every boxed OS/X worth owning.
Interesting how much sparser the packaging got over time. Tiger (10.4) is in a big box, Leopard (10.5) is in a CD-size box with an elaborate unfolding insert, a thick manual, and holographic artwork, and Snow Leopard (10.6) is in a flimsy white crushable cardboard packet with clip-art. The 'grey discs' are non-retail machine-specific installers of 10.6.4 (iMac) and 9.2.2 (PowerMac G4.)
I'm still missing the holy grail of 'grey discs', an install set of Tiger for x86 machines (all big box/retail Tiger versions are PowerPC only.) They're hard to find but they do exist.
Incidentally my big box Tiger is still sealed(!) Not that I'd have any qualms about opening & using it. I'm installing Leopard on the G4 for now though.
I wish they'd done a physical media release of Mountain Lion (10.8 ), my favorite version for x86_64 systems, but it was all digital-only by then. Everything afterwards went downhill. Mavericks is Mountain Lion with added bloat & bugs, Yosimite was the Herald of the Dark Times, and 10.11-10.13+ are the Dark Times. Ah well.
(At present I don't even have a downloaded installer of Moutain Lion if I ever want to revert my Macbook, which is running Mavericks. Should sort that out before every way to get it falls off the internet.)
