This is a video to demonstrate the new netlist-based audio implementation in MAME for the audio board used by Exidy's "Fire One" arcade machine, circa 1979.

Prior to the advent of commodity sound-generator chips in the early 80's, arcade machines tended to rely on bespoke collections of analog parts, arranged to generate sound effects when triggered by the main CPU (if indeed the arcade machine had one). Thanks to years of effort by MAME contributor "couriersud", MAME can now simulate these circuits at a component level in order to generate sound effects in real-time or almost real-time. It's broadly similar in principle to circuit simulators such as SPICE and its derivatives, but can be made orders of magnitude faster.
