Good luck finding old-school Mac software for those. Mac abandonware sites should help. I had a Powerbook 180C that I picked up at a flea market around 1998 (for $15!) that I used for years. It was a pretty useful machine in the late '90s, even though it was pretty old even then. I also picked up other old Macs to try and get working, but most didn't even fire up. A nice Powerbook Duo with the DuoDock, for example. At least in the early days of the internet there were still archives of old Mac software that could be found. I'm not sure how many are still out there. Again, good luck and happy hunting!
