My favorite Slackware memory was how the version I downloaded disksets of (on a 14.4k modem, yeah) had a broken bootloader. Not sure of the Slackware release, but it was kernel 1.2.8, before the ELF transition. Anyway, every time I reinstalled, the bootloader hung on `LI` because the config was just broken, and I had to remember how to fix it.. every time.
So many hours recompiling kernels. My 4MB-equipped 486 took about 8 hours per. I only realized many years later after somehow finding the $400 for a memory upgrade, that it was only slow due to swapping. Going from 8 hours to 10 minutes was eye-opening.
X11 failed to run, for the same 4MB reason. I mean, it would launch, but I want to say it took 20 or 30 minutes.
