Dear Syntaur.com team,
I own a Yamaha DX7s with serial number ND01527, and I’m interested in upgrading its firmware.
Could you please confirm whether my unit is compatible with:
• Version 1.8 firmware
• Special Edition (SER-7) firmware
If compatible, I would also like to know:
• Which EPROM chip model I should use for programming
• Whether you offer pre-programmed chips for my serial range
• If any hardware modifications are required for installation
Thank you in advance for your support. I look forward to your guidance!
Best regards,
Alessandro
