You can print the binary out on a printer in 1-0's and crawl around on the floor reading the billions of bits till you get to PE field called CHARACTERESTICS at offset 0x0FE or you can use a hex editor to do the same. Or you could write a script or a program to do the same. Or you could use Dependency Walker which will tell you plus much more information.
