From the project

Reverse engineerte Hardware aus deutschen Spielautomaten.

Diskussionen rund um die Entwicklung führe ich generell auf dem Automatentreff Discord: https://discord.gg/CEFa4MkQmW

Fertig sind: - Initialisierer: ein Init-Stecker für weiße CPUs. Hat 2 Taster. - ServiceTastaturWeissFake - das ist ein simpler Nachbau einer Servicetastatur für die weiße CPU. Dadurch das sie simpler ist, sind überall die Zahl 0 auf halber Helligkeit zu sehen. Verwenden lässt sie sich trotzdem. - ZLKhalter: Anscheinend beraubt jeder, der Zulassungskarten beschreibt, einen Automaten um diesen Halter. Katastrophe. - Zulassungskarte: Neuere mit Atmega48.
