Apple PowerBook (3400 series) - Manual (Page 207)

Congratulations on the purchase of your new Macintosh PowerBook
computer. Your computer is designed to give you the highest performance
combined with real ease of use—it’s easy to set up, easy to use, and easy to
expand. This book will guide you through the setup procedure, tell you how
to expand your computer, and provide many tips on using your new system.
Your computer is powered by the new † ™ microprocessor (or “chip”).
This microprocessor was designed by Apple Computer, Inc., Motorola, Inc.,
and IBM Corporation. The † microprocessor uses Reduced
Instruction Set Computing (RISC) technology to deliver very high
performance at the lowest possible cost. The † RISC microprocessor
represents the state of the art in microprocessor design.
Your new computer will run almost all your existing Mac OS software, but for
best performance and greatest speed, look for the new software programs
designed especially for computers with PowerPC microprocessors. You’ll find
these programs at any software store that carries Mac OS products.
