An ALU is an Arithmetic Logic Unit, basically, it does math. In a simple form, all you need is an adder and some way to form the binary compliments. That allows you to do addition, subtraction, and with a higher level program, multiplication and division. Of course if you have those, you can do roots and powers, with an even higher level... The takeaway is an ALU does math, and can be simple or complex
Wow another awesome computer! :O +1
@DUC: Yeah I see ARAY more often nowadays than INWR. Eh old habits die hard, it's just what I do. I of course use ARAY where it's inevitable.
@LithiumJanus: Designing is up to you (i.e. what you want it to do and how). Did you read the part in the manual about the breakout box? Bump me in PM if you're still stuck.
@LBPHacker I usually like to use ARAY instead of INWR, since I use PSCN a lot and INWR can get sparked.
Note that that's just how I do things. Others do them differently. Every subframer has their own style, so to say. You know how all programmers write code differently? Well, subframe contraptions are basically programs written in a very esoteric language, as mark2222 once put it.
@NoVIcE: There is a reason for using INWR instead of FILT in some cases. What's nice about INWR is that DTEC stops changing ctype when is finds INWR, so INWR can be used to protect FILT from DTEC. Another reason is that INWR can be on the top of a stack, unlike FILT. I often need a particle that can be on top so I can hide stuff under it and that lets BRAY through. And DMND is better than INSL in general, as it stops CRAY too. I tend to only use INSL for barriers that are sometimes destroyed.
@NoVIcE, I really wish you at least had Discord so I can send u dm's.
