Ditto. I started my linux journey with Slackware 1.0 that I got in a book. I quickly got tired of dual booting so I picked up a used 486dx66 on Craigslist. It even came with a green on black 12" CRT! I took a class and started hacking on the kernel to learn the innards. I fixed a semaphore issue, improved the task scheduler for performance and constantly rebuilt the kernel for performance (before modularized drivers were a thing). I learned not to panic from a kernel panic.

Slackware's "package manager" was a notepad next to the computer. I switched to debian later and loved the whole idea of a package manager. Mostly because it was a trove of free software, but also because it would handle all the dependencies for me and cleanly uninstall (at a time when disk space was valuable).

Those were the days! Long live apt & apt-get!
