Now that's something I've not tried, is using relays for logic.
That means you must be an expert at designing snubbers then :-)
You should have gone for broke, and done a 4 bit adder.
Then your next step would be a calculator made out
of relays.
We had a guy at work, who liked to design asynchronous
logic. His circuits always ran faster than everyone
elses (because... they didn't wait for a clock edge).
But designing those (without computer assistance), is
a lot of work. As you need cover terms so stuff does
not glitch. There were even commercial companies
interested in the idea, but it kinda died out. At least
he didn't break anything. I could trust him not to
blow up a project. He wasn't a kook.
*******
Some engineers are known for their weird fixations with components.
My manager hired a guy, he was mostly non-communicative. I couldn't
say there was a language barrier, as we never had any conversations
with him.
He was given a specification to work with, and he went off to design it. Months went by, he was wire wrapping it in the lab and so on. Well,
nobody pokes around someone elses design (unless it is design review
time). And being non-communicative, he wasn't partnered with anyone,
he didn't ask any questions and so on. In other words, no one at
all was able to learn anything about exactly what he was doing.
So one day, he tells the manager it is finished and it is running
in the lab. The proof it is working, is one red LED. If the LED
is lit, it's working. If the LED is off, it's not working. (This is
a bunch of status circuitry, monitoring logic operation.) Well,
the thing was built entirely out of hex packs of transistors.
All the gates (it's a digital logic function) were made from transistors. There was no jelly bean logic on the board. There must have been
hundreds and hundreds of transistors. Then the guy says "he's leaving"
and he is gone, just like that. We never heard from the manager, exactly what he thought of this :-) But, another lesson learned about
handling people.
If you're going to make a fetish about designing with relays,
don't tell anyone :-) And pretend to be non-communicative
while you're building your contraption. Seems a good strategy.

See my other post in the thread about Petzholt's 'Code' and his
interactive website.
https://www.allaboutcircuits.com/worksheets/electromechanical-relay-logic/
The circuits could get complex with inputs from pushbuttons, limit
switches, electro-mechanical timers, and other hardware. You were building
a state machine with 120 VAC components.
Solid state slowly entered the industrial field. Square D, a major
supplier of switchgear, came out with NORPAK. There was an assortment of modules and back planes to mount them in. Programming was done with wire jumpers similar to the Dupont wires used with solderless breadboards. They were more secure since you used something like a automatic center punch to set the taper pin.
The problem was the NOR gate is the easiest to create with transistors.
Try designing logic when all you have is NORs and inverters. You start talking to yourself.
Next up was the programmable logic controller (PLC) which is used to this day. I never worked with them as I'd moved on to straight 8080/Z80 controllers.
At the time the interface used the metaphor of relay based ladder diagrams that was understood by industrial electricians. I was surprised when I interviewed a candidate who had experience with PLCs and he said ladder diagrams are still the most popular interface.
Logic is logic. We built plastics molding systems and the hydraulic
circuitry also implements logic with spool valves, check valves, and so forth. Air logic is the same. I've used that for explosive environments
when you don't want sparks.
https://fluidpowerjournal.com/design-efficient-air-logic-system/
Fluidics is similar but can work with no moving parts at all.
https://en.wikipedia.org/wiki/Fluidics
It's all logic.

Note that the pages are interactive. In chapter 8 he relates relay
circuits to the logic symbols. In the text he says you could build an
adder with relays -- a lot of relays.
It's an interesting book by Charles Petzhold who wrote many Windows programming books. It reads like it was written for young adults but some
of the concepts get pretty deep.

This SVG (Scalable Vector Graphics) file is a representation of the 6502 at transistor level.
The size of the transistors is intended to show drive strength, some
bus driver pads having more milliamps of drive than other signals.
https://davidmjc.github.io/6502/cd.svg
( https://davidmjc.github.io/6502/ )
It you're the right kind of person, you'll now run off and make
one of those out of transistors (and then we'll see a picture of
your contraption on Tomshardware).
That at least gives some idea how simple the things were inside,
at least compared to the billions of transistor-equivalents in
a CPU today.
