This is a remaster/modernized version of my first complete redstone machine (complete meaning, fully assembled with a UI and all, not just an assortment of wires/gates that I'm testing out or whatever) from October 2012. This is not a successor to the Numerophile Black, just a sort-of "spin off" as a way to celebrate my origins with redstone (hence the name) as well as the Numerophile's 6th birthday.

It is a 1-bit half adder with basic memory controls and an on/off switch.

History/Background
Although I've only been uploading machines here since 2016, I've been toying around with redstone since its addition to the game in summer 2010, though I didn't really get in to it until I saw the first RedGame computer, and later Bennyscube's 3-Bit Computer video. These were the days of having to rely on the likes of INVedit and downloading custom superflat maps that other players had made in MCEdit or similar (as the ability to generate your own wouldn't come for some time). That's not to say I've got almost 12 years of redstone experience - far from it. Usually I'm in to it for about 1-2 months during the year, and don't think about it much otherwise.

This machine was the first "feature rich" one I've ever built. Completed in 2012, I had spent the previous year or so experimenting with "one bit half adders." Starting off with large, inefficient designs, gradually shrinking it down to just a single logic gate. At the same time, I was figuring out what all you could do with pistons, as well as memory. This machine was the culmination of all 3 of those experiments as a way to "graduate" from focusing only on these 1-bit things, moving on to bigger/more capable machines.

It featured a power switch, pistons that enabled/disabled certain parts of the circuits, and some memory to which you could save your outputs. In the original machine, the "memory" was just two RSNOR latches as they were the simplest design and the easiest for me to grasp. Each possible input (of either 1 or 2) had its own "dedicated" RSNOR latch, with some weird stuff wired to it so that the state of the latch only changes when one of two "Save" levers were turned on...or something like that. I don't remember much of the details of how I approached some of the stuff here, but that's okay because this remastered model does it better anyways.

The Remaster: What's The Same
The interface wall is the same size, the features are identical and the buttons/indicators for them are placed nearly block-for-block where they were in the original (the original's layout was actually uneven - check the screenshots and compare). The adder design is the same, and the memory still uses an AND gate system to determine when it's "full." Originally, this remaster was going to be a full 100% accurate recreation, but as I stated earlier, I don't remember how I did some things, and only one screenshot of the original exists so eyeballing it wouldn't work without seeing other angles.

The Remaster: What's Different/New
Aside from the adder design I don't think this remaster has anything in common when it comes to the wiring and layout. The superior memory design and power management circuitry played a huge role in making this thing more space-efficient. The memory controls are different now - in the original, you had two levers hardwired to the two RSNOR latches. I.e., the left lever could only save the value "1" and the right could only save value "2." With the new memory design this sort of control setup was not needed, so is replaced with a single write and single read control.

What Came Next
After I finished the original machine in 2012, I would go on to build this unnamed 4-bit adder/subtractor roughly six months later, borrowing almost all of its design from bennyscube's calculator. That screenshot too is the only one of it that exists, and the world file was lost many years ago. I would build some slightly more advanced versions of that, then took a break for about a year and a half. When I came back in 2016, I built and uploaded the first Numerophile here to PMC, where I've since released 5 successors. Funnily enough, the original Numerophile was also a remaster. It was just an updated/better-laid-out version of that unnamed 4-bit adder/subtractor I linked up there.
