Found this. From what a friend tells me the 27256 chip in the socket contains bitstream code for an FPGA that isn't in that QFP socket, so maybe if we can find that chip we can see what this board does. Board seems to be made by interactive network which according to a few pages they were involved with the Sega Channel (didn't make it but they had plans to expand on it). Other than this, we are kinda clueless at what this is. I haven't plugged it in yet since I want to first find that QFP.
I really doubt the missing chip is an FPGA. The whole point of FPGAs is that you can reconfigure them electronically, so it wouldn't make any sense to put one in a ZIF socket. I also suggest you check the battery - that DS5003 stores its program in external SRAM in encrypted format, so if the battery is flat then the program will have been lost.
If that Dallas chip is anything like the ones found on certain arcade boards then a dead battery means a dead board.
