I've had my mac plus for a while know and with that have downloaded and transfered heaps of classic games and stuff, the only problem I have been encountering is input. With a lot of games they require some form of analog input e.g. a mouse or joystick, when we run games like this on modern machines there is almost absolutely no problem whatsoever because we can utilise almost any USB device as an input when properly configured. With a mac plus this is not so much the case to my knowledge and when playing games like shuffle puck cafe the mechanical ball mouse just doesn't cut it. I know that the mac plus appears to have a DE9 serial port at the back which the mouse connects to; does this mean any serial joystick / mouse seeming it would just send analog signals. Would the second button have no effect / the same effect a the mouse 1 button. Would anything like this intended for the apple ll work on a mac plus? The other thing I notice is that the mechanical ball tends to give me a slip like feeling when I use it; so for example if I need to move the mouse rapidly between to locations it will tend to slip and give me the sensation that I keep running out of desk space to move the mouse far enough to get it to the location I want it to be at. So if anyone has some suggestion for a good joystick like input device or maybe even a better mouse I'd be more than happy to hear about it. I also remember seeing a laser mouse for the mac plus on ebay at one point :\ it was the type that used a silver grid base to help tell the mouse which way it was being moved, think something like that would be any better?
