Need Help! EVEL-8 v.1 FC

I've put together a older ELEV-8 quadcopter kit. I'm unable to get the flight controller to work in any way. No power. Can't find a link for firmware update (just get 404). When I hook the esc directly to the receiver (FS-iA6B from Flysky), the associated motor responds appropriately from the joy stick movements on the transmitter. So Tx, Rx, esc, and battery power are all good. Insert the FB and nothing works. While the battery is plugged in all four motors wiil beep and twitch. Acting almost like a prop lock function. But no status light off the fc board. Could the board be cooked, does it need a firmware update, where would I find such? If I were to replace this board what would the community suggest.
