Dept., Swiss Federal Inst. of Tech. (ETH-Zurich) Lines: 37 Keywords: Vax, CPU, Speed Hello, I would like to ask a couple of really simple, stupid questions. If you're irritated by stupid questions, maybe you better hit the 'n' key... I consider myself a pretty good programmer in a variety of languages, however when it comes to hardware, I only know a little, and that's mostly about PC/AT's and the like. So my questions are... What are the CPU's in the following computers: PDP-11/45 Vax 11/750, Vax 11/780, Vax 11/785 Vax 8600 Do they have individual names? (as in '386). Are they proprietary products of DEC? Was I correct to group them the way that I did above? I am confused because most people refer to these processors as "vax", what exactly does that mean? Furthermore what is the difference between an 11/750, 11/780 and 11/785? What are the associated coprocessors available? References to books or articles would be great. I am not interested in starting some sort of wierd argument about which might be 'better' etc. So I would suggest mailing responses rather than posting them. Thanks for your patience.
