Assuming you have full schematics and everything is simple logic(ie no analog) , I wonder if a CPLD might work better. You may be able fit all the logic from that board into one chip. You might want to take a look a Xilinx. Their fpga/cpld development kit is free and you can get cpld boards from digilentinc.com The development software also has a schematic input mode, so you do not have to learn verilog or VHDL to do the programming.
Not meaning to discourage you from building a board, but you may be able to take advantage of todays technology to make your job a little easier.
