 This project emulates the [Timex Datalink Notebook Adapter](https://user-images.githubusercontent.com/820984/187855124-5e84451c-f65b-4903-a9eb-f44ddde78eb1.png) for early [Timex Datalink watches](https://en.wikipedia.org/wiki/Timex_Datalink) in Arduino!  It is 100% compatible with the original Notebook Adapter, and works with vintage and modern computer hardware.
 
+This Notebook Adapter emulator is tested to be compatible with:
