MHRD is a game in which you write a complete CPU from scratch, starting with nothing but NAND gates. In this stream I complete the game. You can buy the game here! http://store.steampowered.com/app/576...  …...more

this is great stuff, a good way to also polish on some boolean algebra and digital logic. never thought i'd need demorgan's theorem until there's need to convert OR/NOR stuff to AND expressions. thanks for sharing another interesting video.

i like your ingenuity on getting the multiple-bus versions on some of the circuits without using it's simple versions, for instance using 4 MUXs to create the MUX4B. shows there's more than one way to get to a solution. this is a fun exercise, highly recommended.

Hey Bisqwit, I'm just now taking a course on Digital Logic and Comp. Organization and i gotta say i'll have to give this game a whirl. Though it's fun to watch you work through the problems. I did a lot with digi logic back when i was 13/14 but that was, what 8 years ago and while i still have my intuitions i have forgotten most of how to actually do it well. Anyhow, I really enjoy your videos, thank you.
So they made a game out of a hardware description language !? learning verilog was fun, but this i must check out!

This looks like someone took the NAND2Tetris course and marketed it as a game.
the game is 10 dollars and I never spend more than five dollars on a game so I will stick with my fpga and Verilog for now but when this goes on sale I will buy it because this looks fun

Can I play this game with no relative knowledge and just follow the instruction? I try it a bit and it is confusing. Should I learn something about it before start to play?

At 0:01 on the left What is "Steam game 2"?
Was there any particular reason you avoided MUXs early on?

Seems like there is 0 volume
Do you own an IBM beamspring keyboard?
