antiX worked well out of the box on a 2005 laptop
I don't have a lot to tell other than I have a 2005 Dell Latitude and I installed antiX on it. Install was smooth and easy as pie. I downloaded and flashed the 32bit iso. The installer wizard is easy to set up. I had to set my clock manually, which worked fine. I couldn't get wifi working so i plugged in ethernet. I will possibly try wifi again later. I used a combo of the ROXTerminal (which is what i usually rely on to set things up on computers) and the Control Centre, which i've never used before but found painless.
That's about it. Everything works super well! I'm impressed that antiX made my 21 year old laptop usable.
I've also run antiX on a couple 2015-era laptops and desktops, so that of course works great. I installed full, added i3, then removed the other WMs.
