At work we have a small appletalk network with 3 macs and  couple of printers.
We also have a PC that has some specialized accounting software that we would 
like to operate from any of the macs. We have Soft PC, and I have found that the
software works just fine under it, but I would like to have all of the data
for the program reside at one place (the PC hard disk). So my question for you
is(actually questions)

 1) is there a board for the PC that will allow you to hook into an appletalk
    network?

 2) if #1 is possible, is there any software/hardware combination that will 
    allow me to mount the PC hard disk as a networked disk on the macs so I
    can use Soft PC to run the application?

 3) if #1 or #2 is impossible, is there any other way to accomplish what I am
    after?
