What is it?

This compact Apple II floppy disk emulator lets an Apple II, Apple II Plus, or Apple IIe load disk images from an SD card instead of relying on aging 5.25-inch floppy disks. It includes the STM32F411 BlackPill controller board and SD card interface needed for the emulator itself.

What's in the box?

Package includes: 1x Apple II floppy disk emulator board assembly, 1x installed STM32F411 / BlackPill controller board, 1x OLED display and four-button interface, 1x prepared SD card / microSD card, and 1x ribbon cable for the Apple II floppy interface. Apple II computer, Disk II controller/interface card, and copyrighted disk images are not included.

Installation

Connect the emulator to the Apple II floppy interface using the included ribbon cable, insert the prepared SD card, then power on and use the OLED screen and four buttons to choose a disk image. Basic Apple II hardware knowledge is recommended.

Warranty

Hardware is tested before shipping whenever stock is available. The product includes a 1-year non-transferable warranty covering manufacturing defects. If compatibility or setup issues occur, contact support before requesting a return.
