 .03.2016: This is the first time, that N-command has been publicly documented, after [[User:martin]] started reverse-engineering the Coin validator firmware.
+===== The proper way to program coin validators =====
+The original software used to program these coin validators ist called VAL-ESC, a itty-bitty-shitty DOS-application that also just issues the previous commands to calibrate a device, download the current coinset, or upload a new one.
+There is a repository of some coin sets, that we should probably put online at some point in the future.
