[@mrpyfisher1995]

The most fascinating thing about the ALU that I learned in one of the courses I took some time ago was the multiplexer. The fact that in some implementations, calculating all the operations with the provided registers and then just selecting the result through the use of the instruction id all in terms of circuits is a reasonable approach (and I understand it to be one of the more common ways of doing it) is just so beautiful (in the 'mathematical' sense) to me. Although in any case, doing it the other way around would perhaps complicate things in any case.

you should try making components with the new calibrated skulk sensors.

[@niklasliesch4505]

I've been building Redstone Computers for awhile. Seeing you build one was really fun. I think you did a great job explaining the basic concepts. But there are a few more additions neccesary for the computer to be complete. For one there needs to be a stack to store return addresses when calling a function. And there needs to be a way of indirection (pointers), that allows to use data stored in a register as address to access other data. This allows for the implementation of complex data structures like linked lists.

[@Hannah-ck3od]

Not really. This is a fully functional programmable computer, and while functions are a nice thing to have, it does still count as a complete computer without it. This architecture just doesn't support functions. You can work around this and get similar functionality through software, it doesn't require a hardware change. This architecture uses a save and load command instead of a defined memory pointer register. It seems like it would be an incredibly simple change to use a register address instead of an address immediate to get the same effect. I will admit though that I would not have designed it this way.

[@bluesillybeard]
