You cannot upgrade that board to 2013, whoever told you that is incorrect. That type of board can be upgraded to Golden Tee Complete, which has all of the courses (+Extra courses) from all of the Golden Tee Fore! versions.
You will need that board and hard drive and a power supply as well (I believe for the Red board you can use a standard PC power supply, but I'm not 100% sure. You'll have to look itup) You'll also need an audio preamp of some kind, or at the very least a line level converter for the audio. You'll need a super jamma harness. I'd suggest getting it from gatorcade.com. Their jamma cables are very well done, and have most if not all connectors already attached, including daisy-chained ground wires. ALl you need to do is slide them onto the buttons and you're good to go.
Also, if you are planning on using a TV and not a Medium Res or Standard Res arcade monitor, you'll need a video converter as well. You can use AverMedia's AverKey 300 Pro to convert the video right out of the 3DFX card on the board to SVideo, or get JROK's RGB -> TV converter. Depending on your TV, you may need a sync board as well. You can get those directly from him or from gatorcade.com as well.
Good luck!
