I have 2 pcb's that I can't identify. Neither works and they don't have any numbers or markings that I am familiar with. Can anyone help? The first appears to be a dataeast board with a model #: DE-0351-3 and the second board appears to be snk electronics corp. with a No. 073341 and a Romstar tag, serial number 4800, No. 0083 (not sure about the 3). Pics are attached. Thanks.
