So, like Dale, I As a (part-time) C.S. graduate student I suppose I'm in a position to take on such a project, but I have to say I don't see what the value of it would be. It might be somewhat interesting to folks here that it had been done. But why would anyone else care in the slightest? I picture the conversation going something like this: Me : Hey, I just implemented my own Operating System! Other person : Yeah? What's it do? Me : Well....nothing really. But I wrote it in Ada!! Me: : Hey. Wait! Where're you going? For anyone really interested in toying with this, I have two references that may be handy. "Operating System Design, The XINU Approach" by Douglas Comer and Timothy Fossum implements and explains (and provides) the code for a small Unix-like OS that will run on a PC clone. "The Oberon System" by (I believe) Martin Reiser and Niklaus Wirth goes over the design and code for a small Object-Oriented OS (and compiler!). -- T.E.D. -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
