In another thread...
Regarding the "direct downloadable stuff", after round about 10-15 years, all this 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)
That's some good advice, which begs the question, if you could only backup and save "your personal top five must have programs", what would they be and why? (I considered top ten, but figured that would too much typing for people.)
