Subleq!

[@cerulity32k]

6:42 TIS-100 is HARD. You control multiple "nodes" that pass integers from -999 to 999 back and forth, with stack memory. It requires a lot of skill. This looks insane to even try.

I started building hardware that can run the compiled language (Ben eater style) cause I don't need much logic controlling different instructions (duh) and I only need a ALU that can subtract

[@themcchuck8400]

Thank you so much for pointing me at the esolang community. I'm having so much fun with this. Working up my own variants has gotten me back into programming after nearly 30 years. I remember finding and using a similar esolang on the C64 back in the mid 1980's, when computing magazines had all sorts of programming projects. Of course, they weren't called esolangs back then.

[@Truttle1]

Nice! Which programming language was it?

[@themcchuck8400]

@@Truttle1 I can't remember the details back that far. :( It had two instructions: Increment, and Decrement (jump if zero). Fun to mess with for a while back when I was young. Good memories.

[@douro20]

The ABLE processor in the Synclavier synthesizer uses only the 'move' instruction. It is also worth noting that the same instruction in x86 has been proven to be Turing-complete.

[@AlvinBalvin321]

i just randomly remembered this, and was gonna go into sic-1, but my data got reset or something i dont remmeber switching computers, tho i may have

[@AlvinBalvin321]

on sic-1 it says that it stores the result of a - b in register A: "subleq" subtracts the value at address B from the value at address A and stores the result at address A (i.e. mem[A] = mem[A] - mem[B]).

[@Truttle1]

It does that, since it's a different variant of subleq. It takes a second to get used to...

[@AlvinBalvin321]

Ok, and also I think that’s a bit more intuitive because a comes before b so a -= b is more intuitive

[@okboing]

I also conceived of a language with only one command, called NANDulator It uses an unspecified length binary string, and each command is simply 3 numbers, like this one. (a, b, c) will set c to NAND of a and b

[@cmyk8964]

How would you create control flow?

[@RealLifeKyurem]

​@@cmyk8964 Detailed here: kzbin.info/www/bejne/an_Wi3iJlNeEbbc

[@official-obama]

​@@cmyk8964 maybe the negative bits could be the program counter, and if you also need IO, you can put it between the positive and negative things you might also need bitshifts, because if you need to take the nand of bits in a different place value, then you need to shift them together. you might be able to bodge it in an AutoHotKey-ish way by making it so that the first instruction is even then the operation is nand, and if it's odd then the operation is bitshift.

[@official-obama]

@@official-obama that's an old comment (i think), you shouldn't have replied to it

[@Damjes]

What about SSB (subtract and skip if borrow). It's better because is OISC with one operand!

[@redpepper74]

6:53 heehoo i managed to do it in only 93 cycles :P it's mostly because while I have only 2 commands in my subtraction loop, you have 13 :0 not sure what you're doing with all of those variables lol, sometimes it's better to keep things negative (btw here's the loop if you wanted to see) @SubtractLoop: subleq @divisor, @factor, @CalcR subleq @negQuo, @one, @SubtractLoop

[@faraday4160]

the point this language tries to make is legit. computers became too complicated and it can't be avoided if you want to be at least somewhat sane.

[@KeinNiemand]

This is kind of like that movuscater thing where someone wrote an entire c compiler that only uses the mov instruction

There's actually a lot of turing-complete OISCs. I actually once saw a game engine that uses a variant of BitBitJump to run games...

I usually to some extent understand the languages after you explain them in these videos but for this one I still don't get it

[@SysFan808]

question: how do you immediate numbers into stuff, to make constants? making a computer in turing complete (game on steam where you make computers outta logic gates) using this architecture, and the ram starts out all empty. I don't see how I could Immediate a value without inputting...

[@zoltanpataki1307]

This theoretical arch has both the program code and the variables in RAM/RW memory. In Turing Complete, you can sadly only program a ROM directly, so normaly the code is separate from the variables. What you can do is create a circuit for copying the full ROM into a RAM module (increment program counter by 1, connect the first output of ROM directly to the input of the RAM, address for both is the output of the counter.). When this is done (program counter reaches 255 or whatever is your max storage in ROM), the ROM-RAM connection should be disconnected (switch?) and the rest of the computing hardware should read the instructions from the RAM, not the ROM like normally in the game. This idea of copying the whole ROM into the RAM is necessary for any self-modifying code, and it models modern computers much nicely. Sadly, you will lose debugging functions because after the copying is done there is not much to do with the ROM.
