I am a HUGE sucker for Mac os8/9. I currently have a PPC Mac Mini and a Powerbook G4 that I tool around with occasionally for nostalgia's sake. I used slew of various G3 computers running OS9 as my main personal computers picked from the scrap bin at my dad's job (graphic imaging company) from ~2004 until I went off to college in 2010. I had some kind of modified Mozilla browser (Classilla I think?) that had modern-ish web support.

I've been on the lookout for a good condition G3 beige desktop, that was my first ever computer that was "mine" and I really want one just for the sentimental value.
