       | able to keep a niche (but valuable) business like this going.

       | That was our neighborhoods favorite pinball game. The owner of

       | 
       | Glad to see someone trying to keep these machines going!

       | I'm curious if anyone has considered how to use modern electronic
       | components to replace the old "copper coil"-based mechanisms and
       | such that that fine gentleman uses to replace the old parts? I
       | understand he is basically doing museum-grade restorations, and I
       | fully respect that.
       | 
       | But I'm guessing that finding modern components with the same
       | functionality would be cheaeper and longer-lasting, but that's
       | just a WAG. I've watched a couple of YouTube pinball machine
       | restoration vids and those old machines sure are filled with
       | rat's nests of stuff.
       | 
       | It seems like finding modern alternatives would be a good way to
       | keep the machines alive for longer while also making them more
       | serviceable going forward. Plus, that would be a very practical
       | and interesting project for group of mechanical/electrical
       | engineers, that would likely have eventual robotics applications.
       | 
       | In that vein, I wonder if there are any companies that have
       | created tech frameworks to facilitate creating old-world-style
       | pinball machines with modern infrastructure.

         | The copper coils are usually things like solenoids, never going

         | 
         | In practice doing this would take restoring a pinball machine
         | from a "build/repair it with your hands" project and turn it
         | into a programming project where you are starting at a computer
         | screen the whole time. You would just replace the "brain" with
         | an arduino or raspberry pi, connect it to the existing lights
         | and solenoids, but then you need to program it and then it
         | becomes a different thing.

         | There are still companies making new pinball machines today.
         | The mechanical parts are pretty similar to what they've always
         | been. Energize a copper coil, make a piece of metal move.
         | However, the "brains" have come a long way and are basically
         | just modern computers. Also, everything is far more modular.
         | Old pinball machines were a rats nest of wires. Modern pinball
         | machines just use standard computer cables / connectors.

         | Like others have said, solenoid coils don't have a replacement.

         | You could conceivably replace most of an ElectroMechanical
         | machine's steppers and relays and score reels and things with a
         | microcontroller and digital displays, and there are
         | transitional machines that were factory produced as EM and
         | Solid State, but I think you loose the character of the games
         | that way. The buzzing and thunks and the lamps turning off
         | while it computes and all that is part of the experience.
         | 
         | If there's no way to make the games work as they did
         | originally, sure, make them work again by any means, but while
         | we can make them work like they did, we should.
         | 
         | There's p-roc and p3-roc that offer the basics of a computer to
         | pinball interface board (you'll need at least a solenoid driver
         | board, too). That would probably be the basis of control for a
         | modern enthusiast built pinball machine. Most enthusiasts are
         | trying to build something that fits more in the Solid State era
         | than the EM era though.

         | I think there might be something inherently attractive about a
         | game that has relatively simple rules but a lot of depth to the
         | gameplay. You get that in some video games like Tetris and
         | board games like Go, but pinball adds a unique multi-sensory
         | element. You can feel the whole machine vibrate as parts move
         | and the ball rolls around, and you can influence the game by
         | physically nudging and bumping the machine.

         | Pinball machines are in an interesting middle ground where it
         | seems like a good physics simulator _should_ get you damn close
         | to the real thing, with such a limited scope and size of play
         | field. Like, convincing video pinball ought to be achievable.
         | Nobody looks at, say, football and goes  "we should be able to
         | very closely recreate the experience of playing football as a
         | video game" because it's plainly impossible short of a real
         | holodeck. You can have football video games but they can't
         | replace football, they're totally different activities.
         | Pinball? It looks so _tantalizingly_ close.
         | 
         | But the physicality's important. You play with your hips, it's
         | not just button input or even physics limited to the explicit
         | input interface. Hobbyists get sort-of close with lots of time,
         | money, and clever tricks on DIY systems, but you're never going
         | to get as many of those around and as accessible as real
         | machines that you can go play without building one yourself.
         | Certainly, you can't get terribly close on a general computer
         | or gaming system that's not purpose-built for pinball as a real
         | pinball-machine-sized object. [EDIT] I should add that these
         | lose out on the ability of pinball machines to _be different
         | sizes_ --you build one of these, you're got a max size in both
         | dimensions. You also don't get a real 3D playfield that changes
         | depending on how you look at it, lets you peek around the sides
         | while not playing to get better ideas of how to play or what's
         | going on, and so on. It may be (usually is) rendered in 3D but
         | you can't change your perspective by moving yourself around it
         | --the screen's still flat. Even the very-best simulators are
         | pretty far from the real thing.
         | 
         | There's also something magical about what people can accomplish
         | in the designs within the constraints of having to actually
         | move physical steel balls around. It's like modern movie
         | making-of videos where the answer for every single thing is "a
         | computer did it" and it's just so boring compared with when
         | people had to _hack reality_ to make the magic.
