The FPGA uses a high density 160-pin connection.  You can buy an 
add-on board which takes the high-density connection and breaks 
it out to 4x 40-pin connectors (like IDE cables).

I'm trying to create a board an Am386 CPU will plug in to, which 
then makes my FPGA its motherboard.  I will be the north bridge
(memory and high speed I/O like graphics) and south bridge (low
speed I/O like keyboard, mouse, timer, etc).

I know what I want.  I tend to work in my head more than in formal 
writings.

> What are your goals exactly?

(1)  Get the board designed physically, and ordered or built.
(2)  Assemble the board.
(3)  Write the Verilog code to feed and respond to the CPU's needs.
(4)  Write basic software to test and debug the design.
(5)  Write real hardware for video, sound, network, keyboard, mouse,
     etc., to create a little 80386-based system.

Thank you,
