Firmware V1.0E for SD Musix Deluxe card

This update improves the volume balance of the Mockingboard emulation and adjusts the Volume, Envelope, and Noise response to more closely match the characteristics of the actual AY-3-8910 sound chip.

The default sound has also been refined to sound smoother, calmer, and less harsh. Several minor firmware issues have been corrected, and overall operating stability has been improved.

 

Update Instructions

1. Download the attached disk image and either create a physical floppy disk or prepare your system to boot directly from the disk image.
2. Make sure the Apple II is powered off.
3. Remove the S/W block from the SD Music Deluxe card.
4. Install the SD Music Deluxe card in Slot 4 of the Apple II.
5. Boot the Apple II using the attached firmware update disk image.
6. When the instructions appear on the screen, press the Enter key.
7. Do not turn off the Apple II while the firmware update is in progress.
8. When the update has completed successfully without any errors, you will hear a “Ding-Dong” completion sound.
9. After hearing the completion sound, turn off the Apple II, reinstall the S/W block in its original position, and use the card normally.

Thank you
