Hi, I recently enrolled in a Braille school that has at home curriculum/homework. I am totally new to Braille. They sent me a DTB cartridge for the lesson instructions, but I do not own a player. Are there any other organisations or companies, besides the NLS, that make them, or could loan me a DTB player? If possible, is there any way to own one? Also, I would like to know if there are any companies or vendors that make machines that are compatible with the NLS-DTB cartridge.
