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.

What is it?

A compact SNES-style gamepad adapter for Apple II, implementing the Apple II’s 556 timer-based analog joystick logic with a modern thumbstick breakout. Includes both PCB and 3D-printable case designs.

Why did you make it?

Original Apple II paddles and joysticks are rare, expensive, and rely on 150 kΩ pots that are no longer made. This project brings modern controller ergonomics to vintage gaming and eliminates frustrating drift by leveraging well-documented analog timing circuits and community-tested component tweaks.

What makes it special?

Unlike basic DB9 adapters, this open-hardware GamePad offers a true thumbstick experience with two trigger buttons, fully open MIT-0 licensing, turnkey KiCAD & FreeCAD source files, and STL-ready case models—enabling anyone to build, customize, and enjoy classic Apple II games with modern comfort.
