Maybe you need old BeOS programs,
for any ideas for Haiku,
Or old source codes,
don’t available on Bebist?
Some of them you can find here:

Short registration is needed for downloading,
Another interesting collection (Be.com mirror) without registration:

Impressive collection, and one can register easily even if you don’t understand Polish. But your downloads are not working. I’ve tried in two different browsers.
