My guess -- somebody washed the board, water got inside the switches and they became contaminated (nice blue-green corrosion on internal switch contacts). Had to replace switches as a result.
Rather than replace switches - they cheaped out and just installed wires in the closed positions and left the open positions open.
What Ed said. I have actually done this myself on a hosed MPU board just to get it going but I did eventually go back and replace the switches after I got them in. I've also seen it where you put sockets in and use jumper wires to act as the switches.
Thanks for the info guys. I am going to replace it with another one then. This board boots and works fine other than no switches. Any suggestions on what I should put on it for a price?
ROMs have been soldered in too.
Have you thought about buying some dip switches and installing them?

Yes, my board guy is going to take care of it.
