Re: THOMSON MO6 SOUND CARD
This is so great! Bravo dinoprotest!
Does this leaves free cpu for e.g. display?

Re: THOMSON MO6 SOUND CARD
Thanks Jice. The cpu works only to write bytes at 1/50 seconds rate.
Re: THOMSON MO6 SOUND CARD
L’ordre de grandeur c’est 100 cycles par frame max sur les 20000 disponibles et encore pour certaines frames il n’y a rien a faire, car la puce continue de jouer les fréquences parametrées précédemment. Regarde plus haut le code de dino et la taille du fichier psg. Ça fait pas bcp d’octets a traiter pour plusieurs secondes de musique.

Re: THOMSON MO6 SOUND CARD
To build the board for TO8, as the documentation, the available addresses are between $e7b0 to $e7bf. So we can use /exxx signal togather to /w, E and A0 to A11 to select the sn76489 device. It is very simple.
Re: THOMSON MO6 SOUND CARD
That's very kind, thank you.
I should have found this info by myself ... It's described P127 of the technical manual.
$E7BF seems to be used by SDDRIVE

Re: THOMSON MO6 SOUND CARD
Bentoc, can you use e7b0 ?
Re: THOMSON MO6 SOUND CARD
I think it is ok with $e7b0

Thanks, it's a nice and compact layout.
I will build one and test it on real machine.

Re: THOMSON MO6 SOUND CARD
Bentoc, before you build it, we have to check the correct design. I don't know if you are electronic confident.
I have seen the expansion connectors have the same pinout fron MO6 to TO8. Only two signals, /exxx and /e7cx are named differently because of they points to different memory location.
