Nouvelle update chez Charles MacDonald :

I’m looking for datasheets for the Oki MSM5205 (an ADPCM chip used in many older arcade games) and the NEC uPD91061GD or any related parts. I’ve examined the MSM6585 documentation which is an improved version of the MSM5205, but I’m still curious about the original one. If anyone can help out, please get in contact
