A #puzzle challenge for anyone who doesn't know what to do with their weekend:
Based on the first six examples of #microprocessor program code and the output they produce, work out the #architecture of the micro-processor, what the instructions do, and how the display is wired.
Then demonstrate what the seventh instruction displays by typing out the result.
