There is. My latest creation. A 8bit microcontroler made in minecraft.
Features:
(1.0 version without control room)
-8bit full adder + overflow flag
-8x8bit RAM
-16x8(4bit instruction, 4bit address)
program memory
-64 possible microinstructions (16 instructions with 4 step each)
-uncondintional and if oveflow jumps
(place determined using address written with instruction)
-1/3Hz clock speed 😨

New working version (2.0) has 1Hz clock and new faster instruction decoder.

In 3.0 in addition to that useless bus was replaced with 16x8bit "hardware" stack that can store adresses and data. The clock is going to be yeeted out because it is unnecesary #clocklessisbetter (WIP tho)

Might add more documentation and post it as learning model for CS wanabees 🤔. What do you think?

Somebody ranted about his teacher showing windows presentation and teaching nothing. I wanted to comment that post but i have enough material to make the whole rant out of it.

Well at least you have those presentations! In my school we have 2 IT classrooms one with win xp, 1ghz cpu, 0,5gb ram computers and one with win vista, 2 core 2ghz cpu and 2gb of ram PCs.

Guess what room our teacher is using... of course the worse one! The second one is fine, few years ago another theacher had been using it!

I tried to convince him to change rooms but he is coming up with silly exciuses! (like "server is not working here!", well i fixed it with my friend but why are you even talking about it when you are not using yours in old class!)

PS. That server is useless anyway, every pc is connected to router that is connected to internet so supervisor pc is not mandatory, only acces restriction is enforced by win accounts.

I heard from students from my class (that picked that optional IT course) (i'm in high school) that gimp is not working because pc's are so bad!
Sometimes even notepad frezzes.🤔

Not only class is shite but teacher clearly has no idea what is he doing. (in order to pass the final from IT you need to learn simple C++, up to simple foo objects) and of course he isn not even talking about that! On one lesson about sorting algorithms he gave everybody 10 small pieces of paper with numbers on them and told everybody to sort them manualy, because he didnt know how to do it himself! So there is no doubt they wont be able code it.

I need to mention that i volontered to "clean, fix" that classroom (in order to convince teacher to move). And in that class i saw programms written in c++ on every computer! That means somebody was teaching propely before! 😣

I feel sorry for those guys, they are just waisting time. I would fall for it as well but i decided i can learn coding in home ;).
Well, results are shocking, after 1 month of coding i learned C# and i can basicly make any algorithm i ever wish. I learned about computer operation so well that i can nearly teach computer science. (i helped my friend in usa that is a electronic student with that and i'm very proud of it 😁) and it class still can't even use all 3 loops correctly... 😥 Ok i must admit i have been coding for a looooong while so i had time to learn basic c,c++ and pc operations before, but point still stands.

Why the hell are you wasting life of those studends? Why are you giving them a choice to learn coding WHEN YOU CANT EVEN USE PC YOURSELF?! (that it course is optional so you can apply if you want so)

I dont regret not bothering about it.
