Apple has finally announced upgrades for existing PowerBooks that will bring older PowerBooks up to par with the newer models that ship with larger hard drives and more memory. In the disk arena, you can add a 40 MB hard drive to a PowerBook 100 or 140 for $658 or an 80 MB hard drive to a 140 or 170 for $778.
Apple has also bundled the two basic hard drive upgrades with RAM, so you could get a 40 MB hard drive and 2 MB of RAM bundle for $958, and the 80 MB hard drive 4 MB RAM upgrade bundle for $1378. All of those prices fit into the abstract concept of suggested retail price, so I have no idea what your dealer will actually charge. However, if you're not in need of the Apple imprimatur, you can almost certainly do better price-wise from mail order vendors. One way or another, have your dealer to install this stuff - the PowerBooks are trickier to open and work on than even the compact Macs, and there are a few easy ways to waste your motherboard.
The 80 MB hard drive and the bundle with the 80 MB hard drive and 4 MB RAM are available now from both your friendly local dealer and directly from Apple by calling the number below. The 40 MB drive and bundle will be available 15-Jul-92, and all of the upgrades will carry the standard Apple warranty.
Apple -- 800/SOS-APPL
