Very interesting read and a neat product from a technical perspective. I'd like to know the specifics of the data structure used to compress and index the text.
MAME is a really impressive piece of software. It emulates tens of thousands of machines and goes into painstaking detail to get things right.
One of the coolest aspects of their codebase is the ASCII-art diagrams of arcade circuit boards[1], dip switches, and memory maps. These are used to help document each machine driver.
I think electrical/phone sockets were placed at that level because many telephones were designed to hang on the wall (docking onto and covering up the faceplate) for easy access. My childhood home had one that we used this way before we got a landline.
Do you have any links to these discussion posts? This sounds very interesting, and I'm intrigued to learn more about the hardware explanation for this phenomenon.
