Important information about your upgraded PowerBook Your Macintosh PowerBook contains a new logic board, which provides enhanced performance. What has changed in your PowerBook Your computer has been upgraded with a PowerBook Duo 2300 series logic board, which uses a PowerPC 603e microprocessor. The upgrade gives your computer PowerPC performance and lets you use standard Macintosh application programs and "native" applications that have been specially written for the PowerPC microprocessor. You will see significantly faster performance of your applications if you upgrade them to versions that are native for PowerPC.
