Wish I could, Tom. But that photo not only suffers from being way to small and way too distorted, it's also not very crisp. Some photo op advice:
1) Mount your camera on a good tripod. (Don't have one? Buy one. I did, and I don't sell on EBAY or use it daily either.)
2) Reduce your camera ISO to the lowest setting to ensure a noise-free shot.
3) Frame up the CRT screen straight-on. (Don't shoot it at an angle.)
4) Ensure your camera is set on a 2sec timer so your pressing of the shuter button doesn't blur the shot.
5) Shoot.
6) Optional: Color correct and sharpen in an app like Photoshop.
If you do this, you will shoot lovable photos of your classic Mac's CRT, similar to this.
(Sorry to hassle you about this. But I just love big, crisp, non-distorted photos! I also really want to see what your eyes are seeing, which I cannot now with your current photo.)
