All of the above links will guide you to the information you need, but here is a basic summary of the answers to your questions-

The old control system is programmed in C, typically using the MPLab IDE. Easy C is a visual C option, but wasn't used very much. You download the code via a serial cable, so chances are that you will need a USB-serial converter.

As for the wiring- You'll find that it is incredibly similar to the current control system. The easiest way to learn this is to check out the wiring diagrams. The main difference is that the big blue power distribution board in the current control system replaces two separate boards in the old system- the gold maxi fuse block (for motor/victor power) and the black fuse board (for lower-power devices).
