Note: MacZip requires at least System 7.0 and a Macintosh with a minimum of a Motorola 68020 or PowerPC 601 processor. The RAM requirement is set at 12000 K. This allocation is needed only if you compress large numbers of files. For compressing only a few files, you can reduce the preferred size to 1048 K. If you use MacZip only for decompression, reduce the preferred size to 600 K.
