chine with a large rotating memory, demand paging (along with common GC schemes and other among others tricks) don't work at all as well as they did for time sharing. I'm thrilled for Apple, Xerox research, and anyone else who's exploring alternatives. They've met high standards for their graphic interfaces as well. Another disk option: anyone aware of systems that keep multiple copies of a system program on several tracks of a hard disk, taking advantage of seek adjacencies? Typical personal computer design practice is to waste most of the hard disk.
