Slack 2 or 3 here I couldn’t get it to install because it didn’t have CD ROM drivers that worked with mine. Little did teenage me know I could have just copied the disk images to floppies but neither the sound or CD would have worked. I actually just installed it on a VM in Proxmox a couple weeks ago though. Now my windows 3.11 can telnet into my slack 2.3 box because why not.

Could be a number of things. Battery life has significantly decreased. Can’t run recent Android versions, no longer getting security updates, or even software not running because the Android version is no longer supported. I’ve had 3 phones in the last 15 years or so (still on the 3rd) and I still have the other two and they run, but not for long without being plugged in.
