In this manga GTO, there are several references to Macs. These take place around 1999. In one issue, a teacher gives another teacher his old PowerBook (I can't remember what it was) when he got a G3 powerbook. Also, at one point, the main character smashes this same teacher's brand new B&W G3 Powermac and B&W CRT. It doesn't just show them, though. He actually yells "My brand new G3!"
Also, in the cartoon Home Movies, the main character was using a laptop with a grape logo to write movie reviews.
