Hi,

Sean, hap and myself are doing a study of H8 microcontrollers used in chess computers. We have a lot of them identified, but we're still missing quite a lot.

Here is a list of chess computers that we would like to receive some pictures of their motherboard where we can see the microcontroller and read its reference. You can send the pictures to my e-mail address (link). Thank you very much!
