I have two questions ,

1)could anyone tell me the differences between 80387 and w3167 math
co-processors? I saw the fortran benchmark results  for two 33mhz 386 machines,
one with 80387-33 and other  w3167-33 and also saw w 3167 makes machine
about  70%  faster when comparing with 80387. But what is the diffences
in software? Can we use both working with  ms-dos and programs like
autocad? And can we  say both compatible with each other?  What are
appoximate prices for them?

2)here, some peoples use 720k 3,5inch diskettes as 1.4 mb diskettes.
They punch them to make hi-density and then format them. As i can see
diskettes works really well.

Your comments will be very helpful.
thanks in advance.
