In a previous article, I revealed one of the secrets to MartyPC's accuracy, hardware validation. To summarize, it is a method of using a microcontroller to run an instruction on a real 8088 CPU at the same time as the emulator executes the same an instruction, and then comparing the resulting cycle states (and optionally registers) for consistency.

In that same blog post I bemoaned the lack of a JSON test suite for the 8088 CPU. I'm happy to announce that as of now, the 8088 no longer lacks a test suite! With the help of my friend Folkert van Heusden, we have taken three Arduino8088 hardware boards and spent the past week or so generating the first complete JSON CPU test suite for the 8088.
