Why isn't Assembly universal, like regular programming languages?
Yes and no. This is and can be done, but it's very uncommon: https://github.com/lefticus/x86-to-6502

Connecting a 1980s Pinball Machine to the Internet
https://github.com/BallySternOS/BallySternOS
ballysternos is a really neat arduino project that sits on the debug header of old bally and stern mpu boards. the arduino holds the 6800 in halt from the start and re-implements game code
i've seen at least two of these in the wild, one in a Bally Eight Ball running "Eight Ball Plus" code, and another in a Stern Meteor running "Meteor 2021". both add some neat super-features and game modes, the Meteor has an accompanying wav trigger board, speakers, and amp to add wav sound effects as well -- anyone who loves Meteor will appreciate (or hate) that it no longer screams your spinner value in a high pitched tones.

a lot of pinball machines are based on the 6800. i've been really impressed by one project that replaces the 6800 with an avr by just wiring up all the relevant pins and holding the 6800 in halt:

i've started working on a derivative project using an rp2040 instead of the avr with hopes of offloading the 6800 bus work to a pio
