>PDP's have a bus arbitration or granting scheme, DEC had a number of very different processors with "PDP" in their name; I suspect that you're thinking of the PDP-11, and I'm not sure that it is even true for all PDP-11 models. It's certainly not true for, e.g., PDP-5. >Mainframe's as far I knew didn't. Again, there are a lot of very different mainframe implementations, even within the same line. Many of them have bus arbitration. -- Shmuel (Seymour J.) Metz, SysProg and JOAT ISO position; see <http://patriot.net/~shmuel/resume/brief.html> We don't care. We don't have to care, we're Congress.
