Buster Busts PowerBook Disappointment -- In response to our article about the 7.5.3 Update Revision 2.0 (codenamed Buster), Zac Imboden <firstname.lastname@example.org> wrote in with this happy ending: "Upgrading my 520 with the 5300 100 MHz daughtercard was probably the biggest disappointment of my life. The ensuing dispute between myself and my favorite local Mac repair shop ended in a bitter separation. They wouldn't take the card back, despite its dismal performance. However, one of their technicians called recently to announce the impending release of System 7.5.3 Revision 2.0. Overall performance has very noticeably improved, especially the access speed of our 4D client/server configuration. Zowie!"
