Ask HN: What old or deprecated software do you wish was still updated?

Recently I was thinking about older software that is either no longer maintained, deprecated, or effectively in maintenance mode, and it got me wondering: if I was able to revive an old piece of software or something that was deprecated, what would I pick?

Could be interesting to see what Amiga OS would look like if it was still maintained to this day. There are some systems that are binary compatible with Amiga OS that still see a bit of development, but they are mostly niche projects (still very cool projects though).

The short lived BlackBerry playbook

It runs QNX and you could get a terminal emulator for it, through which you had a functional unix like environment with a text editor, compiler, python, etc. It's not updated and all the root certs (I think I'm using that correctly, not my area) are expired, so it doesn't connect with anything that needs https. Otherwise I think it could be an awesome terminal tablet (it needs a better keyboard too)

I looked into MorphOS before, but IIRC you need PowerPC hardware to run it. Is there an x86 or ARM version I'm not aware of?

Debian GNU/kFreeBSD. It was nice to be able to use pf on systems without having to use unfamiliar variants of the rest of the tools.

I don’t believe so.
