After some announcements we revise using transistors as switches. Then we look at how to program our basic 4 bit microprocessor using 4917 machine code.

At the end we see how we can try out our machine code programs using the 4917 emulator on the web page.

  • If you're a machine much like I am, skip through video until about 18.5 minutes in, because he's just talking about "fluff" such as classroom setup, wiki editing, downloading, wi-fi availability, and basic school & forum rules. Excellent video!

  • This guy is a great teacher :)

  • Really thank you, that's really a nice material for me

  • Ah..Now I understand....This is why I became a shithouse cleaner...

  • The guy explanation really impressive.

  • I wanna think like a machine like he is talking like a machine. LOL

  • @eXtinQuish900 ah yes. very clear explanation. thank you! =D

  • @cmonutube at first you use 9 to store the value at location 15 in the register (9 15 is a 2-byte operation) and then you want to store the value in register in memory location 5(using 11).

    11 5 gets the data from the registry and puts it in location 5.

    8 is a 2-byte operation, so 8 prints the value of the next location, which is 5.

    do you understand this?

  • omg, hes wearing shorts...hahaha

  • 47:43 why is it (11,5)?
