The SmartDisk II is an open source project started in 2024 to bring to the community an accurate hardware floppy disk emulator, easy to build.
The full project is available at https://github.com/vibr77/AppleIIDiskIIStm32F411
The full development progress of this project is available on https://www.applefritter.com/content/apple-ii-disk-emulator-using-stm32
If you do not want to build it yourself, I provide via eBay a prebuilt and configured SmartDisk https://www.ebay.fr/itm/306152710617
