Hello i bought a Powerbook Duo 280c from a friend, a while ago and haven't used it for anything but thinking about using it as an Main OS 7 box, but i never used OS7 before what are good apps / games to have on it?
If you have 16+ MB RAM on your Duo, System 7.6 runs well on the 280c. With more (36MB), OS 8.1 is pretty good too. Have a look at the Macintosh Garden for various games:
