Apple said it is offering a modular Macintosh line.

Apple announced plans to market a modular Macintosh product line that will enable businesses to add components to their Macintosh personal computer. Apple said it would offer one mainstream Macintosh computer that can be expanded with a variety of peripheral products instead of continuing to produce two business computers, the Macintosh and the Macintosh XL. The Macintosh XL, which includes 10 megabytes of internal hard-disk storage, will be replaced with a more powerful modular system, consisting of a high-performance 20-megabyte external hard drive added to a 512K Macintosh personal computer.
