Specifically, something like this should work, and will give you the best quality and the ability to capture video more than 640x480 or 512x384. (You could put 800x600 on an NTSC video tape, but it wouldn't look very good.)
As Charlieman pointed out, you may want to use two video cards so that you can mirror the screen for the best performance while working, and of course you will need a modern computer to do the capture. It should work well if your MacBook Pro is form 2011 or newer and if you boot into Windows with it. (It'll be the best with a model from 2012 or newer with USB 3.0.)
There's also this, which has information about a device that'll work with Mac OS X.
Previously, I have recorded my Pismo's display onto a MiniDV tape using a Canon GL-2's S-Video input. It was okay, but the image was sort of fuzzy and although it might work for a game Let's Play, it wouldn't work super well if you wanted to show off anything more involved that benefits from a higher resolution.
The advantage of a tape over just feeding a Mac's video output into its input area is that you get the full performance of your 9600 for whatever you want to record, and you can later capture the tape with whatever suitable system.
