Internet Connected Pinball Machine Shows Off Scores | Hackadayhttps://hackaday.com/2023/02/25/internet-connected-pinball-machine-shows-off-scores/Since the memory for the machine is all in external chips, it was a reasonable idea to replace the CPU with a board that monitored signals on the board. The CPU would plug into this new board, and then a newer microcontroller with an Internet connection could eavesdrop on bus traffic. However, removing the old CPU and jamming pins into the ancient socket was worrisome, so instead, [Eli] elected to tap into a test connector that was already on the board but not plugged into anything.
