Apple may be considering changing their legacy software download page, I had some hiccups just now try to connect to
http://www.info.apple.com/support/oldersoftwarelist.html
....and it said the page cannot be found. It's working again, but I found this alternate link:
http://support.apple.com/kb/TA48312
I will be backing up critical download images to maintain a source for files listed here. I found that this project couldn't be completed easily without the Legacy Software Restore Disk. I recommend to all of you that you download it (just in case it gets pulled or the link goes bad) especially since the rate of decay these days on legacy software is often quite high.
One of these days I'll get to update this page with more content, EG: graphical tutorial on connecting under Win 2003 Server using AFP, hosting an email server, FTP Server under System 6, and so forth. Problem is most of this pertient stuff 1) is forgotten, 2) so antiquated that none of it is compatible any more (EG: SSL/SMTP email), 3) locked up in brains which have moved on to other things, and 4) no longer available due to broken links and general decay of digital media.
As we move faster and push on even harder in our futuristic quest of the utopian "idea" of the future, we leave behind artifacts at a increasing rate, making even a 25 year old computer a relic destined to die.
EDIT: I forgot to mention, with Shareway IP Personal Bgnd running (modified), I could not see or connect to 10.5.8. I think the universal solution is an FTP server, most optimally under System 6 in the case of emergency restore media.
