Here's some comments about the other files:

*** HexVex_Division.mp4
This is a recording of the trainer emulator while performing arithmetic division, as described in the example programs in the Documentation. The dividend and divisor are highlighted in the program editor. At the end of the calculation the correct integer values are then displayed in the Quotient and Modulus registers, at the bottom right.

*** HexVex_Subtraction.mp4
In this recording of the trainer emulator you can see how it's possible manage negative values with the HexVex architecture and therefore handle subtractions. In the Wiring section at the bottom right, you can see register A and register B storing the input values of the subtraction. Once the calculation is performed, the correct result is displayed in the following register, "A-B=".

*** JunctionFunction.mp4
Video of HexVex while running a "Knight Rider" sequence (also known as LED chaser) using the trainer emulator. In this video there's a twist because system interrupt signals have been attatched to each function of the program. The function names in the virtual keyboard will blink blue whenever an interruption happens and the program breaks away from the programmed flow. At the bottom right, the bargraph displays the result of whatever is going on with the program.
