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.
