Adds CompactFlash and USB mass storage plus floppy-image mounting to slotted Apple II and Apple III computers.

ReActiveMicro showed an in-stock, backorderable Add to cart path on 2026-07-24. The included media is preconfigured, but user-supplied images and operating systems still need to be compatible with the selected computer.

Emulates Disk II, UniDisk 3.5, and SmartPort storage from an SD card with an STM32F411.

The project README linked a current assembled eBay listing on 2026-07-27 and also publishes a complete build path. An innoelement assembled variant showed six units on Tindie, but that page simultaneously displayed a shipping rate and said it did not ship to the United States; confirm checkout availability before relying on it. Match the board revision, bootloader, and firmware: bootloader 0.15 has an Apple IIgs SmartPort problem, and boards older than Revision 3 need a trace modification for Apple IIc or IIgs use. Use a quality FAT32 SD card with 32 KB clusters. Never connect an ST-Link programmer while either USB or the Apple II powers the board.
