Ask HN: What’s the oldest software/hardware you still use today?

I still use an upgraded Newton Messagepad 2000 mainly for notes and journal entries. 99% of the time I remember things better with a kinesthetic act, so it's filled with a bunch of notes and other scribbles just because I needed some kind of movement (in this case a stylus on screen) to retain it in my head.

Alas, with how clunky it's been trying to sync with the rest of my digital life, it's currently in Dual-Carry status with a Note 8, with eventual retirement as a conversation starter on my bookshelf.

I have a 1999 iBook clamshell that my daughter now uses for school. It has been upgraded with more RAM and I replaced the slow HDD for a Compact Flash card so it's probably the fastest clamshell of the world...

For basic tasks (homework assignments, simple image/video editing, light browsing) it's surprisingly usable! The only downside is that I had to create a separate, unsecured WiFi network because the original Airport card doesn't play nice with modern security protocols. Oh well.

Apple 30" Cinema Display (2560x1600, 60Hz, dual-link DVI) that I bought in 2005 and have lugged around with me to jobs and homes since then. Still works perfectly.

Not sure if this counts but I still have (and occasionally play with) an Atari 2600.

  For you younglings, that piece of hardware is almost 40 years old.

Might not be as old as some others as I have throughly modernized this January but https://github.com/ddev/git-blameall is very useful: this is a tool similar to git-blame, but it shows every line that was ever in the file, along with information about when it was added or deleted.

I’ve tried, but can’t find anything I like better.

It's connected to a Raspberry Pi these days.
