Finally, my collection of the 49/50 series is complete.

I finally managed to get a blue HP-50g, I got it for $50 USD... Box in Spanish, quick guide in Spanish, French and Dutch. I usually don't keep the boxes but I think I will for this one because of its rarity.

I found a battery replacement option for the Ti-84+ CE and TI-nspire CX CAS II calculators It's the battery from several Dumb-phones or from Samsung Galaxy Pocket Neo I had no problems using it, except that it doesn't charge. This could be due to a battery failure (it's swollen), or because the calculators don't detect the battery's authenticity verification. If anyone else can perform the tests, please post your results here.
