If you have a d10 to spare and don't mind repetitive tasks I would suggest the following.Take d10, roll it 200 times (recording results)
Paint that d10, roll it another 200 times (again recording results).
For a fair die I think you expect to get each number 20 +/- 8 times, where the 8 is from \sqrt{200 * 9/100}
If you have a lot of time you could do more like 2000 rolls.
It is unfortunate that TI3 uses d10 instead of d6...
