Teaching the fundamentals of operating systems is going to be hard enough, let alone turning them loose with a disassembler and a block of object code. And now for something completely different. "Operating System Design, The XINU Approach" by Douglas Comer, of Bell Labs, Published by Prentice Hall, 1984. Rather than showing lots of different ways that something might be implemented, he picks one way, and does a, layer by layer, design of a whole system. He starts with link lists and works all the way up through a file system. He states out front that this is not UNIX compatible internally. On the other hand he claims a big chunk of this fits in 4k bytes, and that the sources are "available at nominal charge". Has anybody got any information on this tape? Don Taylor tektronix!tekig1!dont
