the Chip was programmed with your first(?) ALU Build and went black when accessed, other ALU builds are ok, deleted the problematic chip to not reset my worldposition accidentally^^.
And also have the problems with Megamacrochips facing to the left, the image appears one chip wide to the right.

Hello again^^ tried to acces a remotechip but don't know what was build in there and got:

From what I've been reading, multiplication takes several steps involving left shifting bits from one number and ANDing with each bit in the other in turn then totalling them all up. It can use these ALU's (left shift is effectively A plus A) though the circuit would be quite large in any case.

As for division, I guess something similar is done right-shifting somehow but *shrugs*

I may have went a little overboard trying to duplicate the 74181 ALU chip, heh. A simpler 'cheaty' component that took two input values and performed the selected arithmetic would have been better perhaps. Building a circuit in starbound is already rather meta anyway!

Hm clipboard issue after the first insertation is solved by use of a better program then the base editor it seems^^ The 4 ALU Solution is flawless but a little complicated^^ but its the way probably. We won't see multiplication with those ALU's though right?

Btw the cla is useful when building an 8-bit adder from single parts but not really with the new alus's and comperators for me.

could insert the Sticks finally^^ rebound ctrl key and rebootet pc was the trick i think. 3 ALU Version works like a charm :D thanks and the CLA Module is only the exterior without the main adder?

https://pastebin.com/GtadpYkP for a new 4 ALU test.

hmm don't have any problem with pasting it into my starbound chat. :(

can't insert the spawnitem command text please try if you can, its too long/big or something.

I think I've got it working - with 3 ALU's here: [ https://pastebin.com/XcB2j0hC ] :)

Hmm still not quite right on some matching bit additions. Scratching my head.

ok^^ can't insert the CLA pastebin text into starbound only parts so its too long to copy?
And easier while this is CLA adder totally overflowing me with input variables :D?^^

and checked out the 3rd a+b stick^^seems alright but it flickers so some propagation delay. why actually 4 bit^^ and not 8 which can also do 4 bit operations^^?

Now [ https://pastebin.com/ES1zWNub ] with my new CLA.

For addtion it seems to be 1st ALU P > 2nd ALU, 2nd ALU (P&G) > 3rd ALU (9th bit)
[ https://pastebin.com/mQrPTp1y ]. I've got a CLA in the works to make this easier!

hm works ^^ but^^ i don't understand why the alu connection is only when p g and c-out are all active and why the changed a plus b +1 formual in ALU 2 then generates still the correct result O.o (128 and 8 + 8 example) seems only to occur with 8 (bit 4)^^ and secondly i don't like propagation increasing builds^^ can you add the 3Andgate into the ALU and create a new output instead? wont delay the 9th bit then^^

Hmm, been playing a bit more with the ALU. For addition, pass P G and C-out to an AND3 and then that to the C-in of the next ALU. Think have cascaded two adding/subtracting here https://pastebin.com/HU3JuvLL to some extent.

Checked out the File you gave me and its correct so far with Plus/Minus except two issues^^

Bit 9 is always active no matter what i tried, and ALU 2 can not be set to A plus B but only to A plus B +1

oh remotesensors are still at 250 tiles range in the Standartversion of Macrochips? Read it in the description.

ok got the stick now will continue later^^ thanks so far :)

The /spawnitem should make a vcdatastick pop at your mouse pointer. Works here. As to multiplication... no idea, sorry!

Is multiplication available with the ALU? and hides behind which function?^^

ok how do i spawn your stick again? copied the text and pasted in chat with admin mode on but doesnt work

Going beyond my logic circuit knowledge now I think. I've kinda managed a two-ALU addition/subtraction with this circuit [ https://pastebin.com/iynJn7kW ] - the 9th bit needs more logic to properly calculate but works for A-B results leading to negative values now with S0110 C-in 1 input on first ALU.

And thanks for the comparator :) works with 8bit it seems and is very efficient this will make most addings/subractions superfuild^^

Besides the ALU developement i figured out how to convert an 8bit signal into 256 analog positions^^ And would need an 2x4 bit multiplicated result at 8bit too^^ So but generally i have 8bits data that need to be added/subracted/multiplicated so i only have 4 input slots at the ALU how do i connect the bits 5-8 then?

The trick seems to be how to determine the '9th' bit from the 2nd ALU's G/P/C-out for negative values on subtraction. Answers on a postcard to...

Subtraction did seem to output a twos complement negative number for me from two cascaded ALU's with P > C-in of the higher priority nibbles. A minus B minus 1 (plus C) seems to be the function necessary for A - B, S0110 C-in 0. I've added another component which may be useful here - upload in a sec.

The thing is ALU 1 needs to know from ALU 2 if it can keep the bits active that are in most cases not correct when computing 8 bit numbers and vice versa

Hmm, having some success cascading P > C-in of next ALU for A plus B. Not figured out A minus B yet.

a minus b appears when c-in is active^^ still not clear how to process 8bit data

S0110 should be A minus B, S1001 should be A plus B. I think its working correctly now, just not sure on the uses :)

The 2's complement is normally implemented within the last bit not via c-out^^ since the cascade would also need the c-out for higher numbers

meant the old platforms, when the directiongiver failed the platform turned around and took the right direction after a short while instead.
Ok chips woring alus are up and i want to add(subrakt) 36(A) and 12(B) whih fuction should i set?

Looks like the ALU returns a twos complement negative value, with the C-out denoting positive/negative. Eg, 1111 = -7 in this case.

You mean the lifts like in the stations? If so think those are just wired buttons and scripted vehicle lifts.

And the negative result output was very welcome how do i see ot now?

btw did they gave platform also an intelligent call function?

its ok now^^

Reuploaded. If still not working then prob need to look at your log again.

non alu containing chips also dont work.

They're okay here. You may need to start a fresh circuit to place/test ALU's as the component nodes changed.

oh and Starbound update inc

chips are not working atm

Hmm, incorrect bracket. Not sure how I managed to upload that after testing but fixed.

Getting disconnected when accessing my chips, when relog i start on my ship and if i break the chip it dissolves.

Right, completely revised the ALU script, basing off some code I stumbled across. A lot tidier than the way I was going about it! It looks to match the outputs on this simulation well: http://www.righto.com/2017/03/inside-vintage-74181-alu-chip-how-it.html

The P/G outputs are not useful at present. 'A=B' if all F outputs are high (not each input A is equal to input B which is what I would have thought??) P/G will be useable with the a carry-lookahead chip (the '74182', which I may be adding next.) Ripple carry passing the carry straight up to next should function however.

Blackscreen this time with better reference ;) https://pastebin.com/A50854HV
unistalled longer ship travels btw

That sky.config.patch error looks to be from the mod Longer Ship Travel Time (https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=816819845) not this one ;)

The difference between "+" and "plus"... that confused me too when working out the functions! In logic summations, + means 'or', a + in a circle means 'xor' and line above means 'not'.

another blackscreen and whats the difference between "+" and "plus"?

The old blackscreen with chipreset while playing around with the inputs of the alu:(switched s0 on off on or so)
