description             an emulator of the Macintosh Plus and other early Macintosh models

long_description        The Mini vMac emulator helps preserve software made for early \
                        Macintosh computers -- those sold by Apple from 1984 to 1996 \
                        based on Motorola's 680x0 microprocessors. \
                        The best-tested version emulates a Macintosh Plus, but there are \
                        also emulations of the Macintosh 128K, 512K, 512Ke, SE, Classic, \
                        and SE FDHD, and work on Macintosh II emulation is in progress.
