Thanks to the endlessly resourceful NorCal Arcade Club, and associates, my Astro City and Egret now sport ashtrays full of tokens. Fingering the wire was fun and all, but crediting with a coin is a must for the most legit and pleasurable arcade experience in the home. You just try harder when it costs you coins (which are free to you, though which you initially had to pay for, though you have the key so you can use them again, but still, try harder).
Both coin mechs had to be adjusted a bit since they were setup to accept 100 yen coins, which I only had a handful of. The Egret’s mech needed the magnet removed, but on the AC I had to sand down a metal post to let the larger token pass smoothly.
For some reason I don’t mind freeplay on the American woodies — partly because their coin doors aren’t as easy to open. But on Japanese cabs it just feels cheap to wander up and smash your finger into the 1p button like a dud.
