I 've bought calculators from him, but never bought one modified. He sold recently one 19bII with the modified back door for the equivalent of 100 us dollars.

I have no affiliation with him in whatever way.

Here is a link for an advertisement.

Ask him for some photos, you will be amazed.

If you need some help with Portuguese, just let me know.

Edit: the last photo in the ad is a modified 19bII

That's pretty neat work. I don't think I'd do his mod to a perfect clamshell, but to save a broken one from the junk drawer, it's great! Does his new door system retain N batteries or somehow go to something else, as in the "from the factory" batteries-on-the-back 19BII?
