I still have about 1.200 old Software-CD-ROMs, and at least the same in Audio-CDs. (all ripped)
I do not use them very often, but I like to have them, and to know that I can use them, if I want to.
Regarding the "direct downloadable stuff", after round about 10-15 years, allthis stuff will have gone.
Watch out for so many old TI-99-homepages, and all these links, all this things that have gone, and end up in "Error 404" today.
That´s why I never rely on online available resources, and download and save all things that I want or need.
(...and why I sometimes download & save whole servers today)
