Hallo Franz...

Vieleb lieben Dank

Ich hoffe Du hast den Anhang erst nach meinem Edit heruntergeladen?
In der ersten Version konnte es nämlich noch zu einer Level-Änderung zwischen fixem und blinkendem LED kommen (wieder so ein Conchess-Murks )

Hallo Franz..

Ich lade es mir vorsichtshalber noch mal runter .

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!

Hi,
interesting idea. I have some of these devices. I think it should be ok, if you have ONE picture/MCU-Code of every device in your list? Or do you expect to find different MCU in devices of identical series?

Cheers,
Andreas

Hello Andreas,

In that list are the chess computers, with Hitachi H8 microcontroller, of which we don't yet have a picture of the microcontroller.

Most of these H8 microcontrollers include a "ROM serial" in the part number, in the same way as the Hitachi HD6301 family. At the moment our main interest is to document it, because there are chess computer models that have exactly the same microcontroller (with the same internal ROM) as for example Saitek Centurion, Cosmos, Cougar, etc.

Best,
Gerardo

Thank you, Gerardo, and yes I know that different devices can have same MCU from my own experience.

So I think one sample of each device will be sufficient.

Maybe we can save a lot of work when we tell IN ADVANCE which device we will going to open to get the informations you need...

I can provide you with information on the following devices within next days:
Schachakademie = TCA
Mystery
Centurion
Chess Challenger (should be identical to Centurion, is not in your list above)
Virtuoso

So no one else need to open these devices.

Cheers,
Andreas

Thank you.

Today I have removed 3 or 4 models from the posted list, of which I have already received photos. In the next days, as I won't be able to edit the post anymore, I will write a new post with the updated list (with less models therefore).

By the way, I am not asking you to open your chess computers. In many cases the motherboard is upside down, and it is not possible to see the microcontroller without disassembling everything and disconnecting the sensory board, which I do not recommend if you are not experienced. What I was asking for was to receive those photos that are already done, as there are certainly some.

Best,
Gerardo

Hi,

would this be any useful? (excerpt from RON himself's notes)
MfG,
Tibono

I did a lot of photos... but I can't find them

So I will open the devices (some of them ARE open already ) and yes, no problem, I'm experienced in doing this

Ha, found something I posted years ago: Centurion, Mystery

EDIT:
Picture taken 5 minutes ago. Mephisto Schachakademie is out of order (design flaw) and ready for "Recyclinghof"
