I have been keeping these around for way too long now:
Some good memories in there, like Mac OS X Server 1.0, but as with childrens' television the memory is vastly better than the reality. I'm not sad to see any of these OSes go in the bin, but they do revive happy memories.
Aa reflection on the 2000's, I'll say that the Mac OS X Server 1.0 disc came with a Server G3/400 which cost £4,500 in late 1999. Imagine what £4,500 would get you at an Apple Store today.
