Actually there are alot of things who are better. For example Ben Eater as Lilu_Kuh98 mentioned. On the screen with the clockspeed there is a board with a 32K memory chip between the clockspeed display and the Input/Output connector. This means you don't even see anything executing as you don't see the ram at all.

The main memory isn't the memory in that case, it looks like VRAM if you could call it that. I'd expect a fair bit of garbage pixels around the edges. Sure, maybe they read board state from the display blocks, but they need to store which tile they are moving, and its X,Y position. I doubt this small processor has enough registers for that, as something like that without touching memory would be tricky even on x86, which has a real crapton of registers.

I know that this is a ton of work. And i honestly don't wanna do the debugging to get this thing running. I mean this has a world record for a reason. The thing about this i don't like is the extra memory. Why is this a tetris machine? why. This is supposed to teach programmers how the machine works. so you can follow the instructions and micro instructions. Why on earth are they hiding the main memory? The memory display looks nice, but that is not what programmers want to see. or at least not what i wanna see. I'm pissed about this because i really really love the idea and think this is wasted potential. You don't rage about something when you are not invested about it.

There is not much to say about microcode other than it being a more RISC-like (probably) instruction set below modern x86 and it's highly optimized for the processor design. (I can imagine things like the x86 decoder outputting different parts of the needed microcode sequence into different pipelines to maximize throughput - a level of parallelism that would be impossible to achieve normally), other than that it's quite hard to get a lot of info about it as big companies such as Intel or AMD don't make that info public :P You can however do some interesting magic with microcode, such as "DIV and IDIV" not actually having a hardware divider, simulating 256 bit vector things on 128 bit vector units (Ryzen does this from what I know) and even fancier things like loading new microcode - haven't done any research on this but just saying what I've heard, you write a memory pointer to a register and BAM, suddenly new microcode is loaded :P (basically microcode loads it, does all the decrypting and checking and sets up the CPU internally)

Really cool. Reminds me of building a microprocessor on a breadboard out of logic chips in college. Showing it with discrete transistors shows the entirety of computer engineering from start to finish.

Twice the size of the UK? Even if every pixel only represents 1 bit, that's 8 x 2^30 pixels. Square root of that is 92,681. Assuming the LEDs are about 2cm apart, each side of the screen would only be 1.85km long. So it seems it would be the size of a village, or am I missing something?
