Oh man, I've got the perfect thing for you. Years ago, I picked up a TG16 from somebody who had decided to do...something...to it. I assumed it was broken when I got it but I plugged it in and, lo and behold, it worked.
The area around the screws in the back were cut out with a saw of some sort. Then on the front the area around where a card is inserted is cut out and the RF shield beneath has been partially removed as well. I opened it up and, near as I could tell, nothing was actually changed inside. For grins, I played games on it for a bit but then I stuffed it in the back of some closet.
It looks ugly as sin but still worked fine last I checked. This was, oh, 10 years ago or so. I've had it sitting around collecting dust ever since. If you're interested I'll see if I can find the power adapter for it to make sure that it's still operational.
