Here's just a quick update on one of the projects I'm involved with these days. What you see below is an Grayhound Championship Basketball, an arcade game owned by a friend. The original hardware was a Z80 system, but this is now being replaced with an Arduino Uno.
The current version only supports 1 player mode, but a variety of 2 player modes will be implemented soon.
The arcade to the left contains the original hardware and is working just fine.
The original power supply conveniently provides 0/5/12V, as well as a 110V for the solenoid releasing the basketballs to the player.
The Arduino is equipped with a prototyping shield where we soldered the connector for the back panel and the various buttons in use. A proper, more professionally looking shield will be designed at a later point.
