In the meanwhile, I remembered that, when we played with the BIOS, we saw the mention of a company called Kontron. This might be the company who sold the motherboard to the braille device constructor.
Is this company known by one of you guys ?
yes indeed. A good company. Makes all kinds of embedded stuff.
Great ! Is it worth contacting them to try to get more prccise information ?
Thanks,
Sébastien.
