Hey chipslc, your motherboard is a full-size motherboard. My EZ- Trak is a 2000 model and uses a smaller Single Board Computer (SBC) mounted to a passive backplane, so the Advantech MB I shared with you won't work. I found a refurbished board that matches the one you have:
DFI G586IPC yours is similar to my'97 EZ-Trak.
