The (Unofficial) Apple Archive is a newly launched collection of historic Apple media and video.
It must have been a tremendous amount of work collect and catalogue and, for me, the most interesting years are 2004 and 2005 - the years that lead me to purchase my first Mac (and yes, I did buy into PPC after the intel transition was announced!). I doubt it’ll last - Apple’s lawyers must be itching to write takedown notices - but while it’s there it’s an interesting place to poke around.
I still have that old first machine somewhere and I should dig it out; last time I checked (perhaps 5 years ago) it seemed to run ok. I do hope it’s still in something of a functional state.
