What a coincidence! My local goodwill happens to have a copy of Macworld Mac Secrets 5th Edition. (Don't know if the CD was with it.) Though as far as I know they're not having a book sale, so it would cost $2. So if someone wants it I might be able to pick it up for them. Depends if it's still there the next time I'm there.

This book helped me learn how to network macs with localtalk. And understand networking. Back when I didn't even know how networking even worked!

Congrats on your find Trash80toHP_Mini!
