Sitting between basic adders and full blown computers, the Numerophile series is designed to be capable and also easy to understand. The Numerophile White represents the best of that, so far.

My use of Snow Blocks in this build is inspired by Bennyscube. I am a big fan of how it looks, although I know color coding is preferred among users.

When you download the file, you will have 3 worlds to choose from.

• NumerophileWhiteExpanded is the Numerophile White + decimal display + all 3 expansion slots utilized for the included DMD-2 expansion device. This is the full experience.
  
• NumerophileWhiteBase is just the Numerophile White by itself - no decimal display, expansion slots are empty. This is so you can expand the machine however you want, or maybe you just want to use it without any extra fluff.
• NumerophileDMD2 is the expansion device created for the Numerophile White, seen on the Expanded version. This world includes only the device itself, so that you can use it for (theoretically) whatever you want.

I recommend using the Expanded version first, of course, as it has the most features/most documentation. The Base Model's documentation may be a bit outdated, as it's from November 2019, before the inclusion of an expanded model/decimal display/etc was ever even thought of.
If you have any questions regarding how to use this thing, or how something works, do not hesitate to contact me here.

Note: I'm not quite sure how the PMC world viewer works, but it only allows you to view the DMD-2/expansion device world, from what I can tell. Just a heads up.


Specs

• 5-bit ALU that can add, subtract, invert in and out, zero, generate random numbers
  
• 2.5 Bytes of Memory (10 bits for Inputs, 5 Bits for ALU Outputs, 5 Bits for RNG Outputs)
  
• Material Implication "Co-Processor"
• 4 Displays (on the Expanded Model. Base model has 3 displays).
• 3 Expansion Ports (1x Parallel Input, 1x Parallel Output, 1x Assignable Command [​to control external device, but can be used for the main system's components as well, if you wanted])
  

What's Improved From Previous Systems

• ALU Design: Previous Numerophile machines had a two-story ALU design with an "addition" floor and "subtraction" floor. While the overall design is still the same in this, a new input management system will allow both operations to be performed on the same "floor." In the screenshots you see the ALU in its entirety. Its a big longer and wider, but only one floor.
• The Numerophile 3 had 3.125 bytes of memory. As small as that is, it was still too much. Thanks to improvements in how this system handles data, it can still do all of the same things (and more) while only needing 2.5 bytes.
• Automatic "Input Mode" toggle. Past machines required you to flip a lever to toggle between setting input A and B values. This machine does this automatically.
• Previous machines required a massive chain of multiplexers to determine whether the output panel displayed a sum, difference, or an inverted output. This new machine totally eliminates these multiplexers.
• Better placement of the RNG component
• A binary-to-decimal converter and decimal display make their debut here (expanded model only).

________________________________________________
****KNOWN BUGS****


-When performing Non-Implication (aka, Implicate lever + Invert ALU Output Lever is turned on), the decimal display will show incorrect numbers - 30 and 31 - instead of the correct 1 and 0. Regular implication works as intended. This bug does not affect the base model. This is because, with Non-Implication only, a "Disabler" component turns off the 2, 4, 8, and 16 lamps of the Primary Binary display manually so that only the "1" lamp can receive data. The decimal display, however, does not have this disabler component, so it receives the uninhibited inverted output. I will probably correct this in a future update.
