PowerBooks with 4 MB RAM as shipped from the factory will still have System 7.1 loaded on the hard drive, since Apple recommends not installing 7.5 on PowerBooks with only 4 MB of RAM. These machines will also include System 7.5 as a "net install" option which the user may elect to install. Or, U.S. customers may request a set of System 7.5 floppies for a $10 shipping and handling charge, and sales tax, by filling out a coupon available from Apple resellers or on AppleLink. [MHA]
