[comp.sys.ibm.pc] 80287 coprocessors

aw@duke.cs.duke.edu (Angus Wang) (05/03/88)

I am thinking about getting a 80287 coprocessor for my AT clone to do some
graphics development.  I was wondering if anyone could tell me what speed
processor I should get and explain their reasoning.  I have an AT clone
that runs at 6/8/10 MHz.  The 10 MHz speed has 1 wait state and we've
all gon thru that discussion on the net before.  However I was wondering if
I should get a 80287-8 coprocessor and run my 80286 at 8HMz with 0
wait state, or could better speed be achieved with a 80287-10 while
running my 80286 at 10 MHz with 1 wait state.  Since I have > 1 meg RAM
most, if not all my pixel info wil be in main/EMS memory so I/O should
not place too much of a consideration.
Please respond by e-mail, if enough info comes in and requesta are made
I'll post a summary or forward.  THANKS
