I've used these in

• Amiga on A2091 cards
• Mac Classic connected to mobo SCSI

The LED indicator normally flashes to indicate disk activity.

Upon initial power-on, the activity LED also reports following status conditions:

• 1 fast blink on boot: Firmware successfully loaded, and at least one image file loaded successfully
• 3 fast blinks: No images found on SD card, and then automatically falls back to raw passthrough mode.
• 5 fast blinks: SD card not detected
• Continuous morse pattern: firmware crashed, morse code indicates crash location
• No LED activity: verify the 'BOOT' configuration switch is OFF

If a crash occurs, the firmware will also attempt to save information to a separate zuluerr.txt log file, on the root of the SD card.
