I'm trying to sort out the sound EPROMS on the Sequential Circuits TOM drum machine. Unlike the older Drumtraks, the TOM does not have a one EPROM per voice setup. Instead, multiple sounds go on two chips. From the service manual, I believe the chips have a header which lists the starting address, length and filtering status (sounds go through switchable analog filters) of each sound. Is there any standard way this is stored so that I could create my own to make custom sound chips? Or does anyone have a suggested approach toward decoding this data?
Thanks for any help!
Well, someone has figured it out!
