And on the original Classic, it was to finally replace the Plus from 1986, which was the last Mac still produced that still use the 800K floppy and the old keyboard/mouse interface dating back to the Mac 128K. While the Mac Classic is indeed less expandable than the SE, it still include many of the enhancements from the SE, such as the ADB keyboard/mouse interface, better SCSI, a newer ROM than in the Plus, and support for an internal hard drive, and more.
