Great site. Missing NeXTSTEP point releases (e.g. 3.3 which supported x86 that I cut my teeth on).

It would be good to see other non-Windows personal GUI platforms demoed (like Amiga, BeOS, GEM) and early ones like the Alto.

Actually the point releases can be found in the "Customize..." button next to run when you hover on the image of the release. :)

Nice! Would be good to make that more discoverable.

Heh yeah you have to click through to find it.

Could be as simple as hover text "click to see other versions".

Heh maybe if that's what you need.
