but does this contain the pin outs that the IBM manual does?
I'm trying to build a 16 bit ADC card for AT or better class machines
to interface physcis experiments.  I would like to use the 16 bit
resolution of the AT bus but everything I'm finding is with respect to
the 8 bit slot only.  I've built these things for Apples before but
never for IBM's does anyone know of a good text that would include
everthing you need (for the 16 bit slot).  I found a couple books 
that deal with the subject and an 8-bit card.
                                
                             Any and all help will be apreciated
