I used to work for a video editing company witch used Griffen Powermate jog wheels at each powermac:
They were lots of fun for playing pong. Better than the official atari 2600 pong paddles actually. With an MSRP under fifty bucks, it's not out of range for a MAME gamer on a budget. I wish I still had one of these today, because I've never played tempest.
I'm considering buying one now. In the interest of thrift, I might just try using my trackball as a spinner. Come to think of it, I have one of those atari pong paddles (the type with two paddle controllers connected to one 9-pin interface). Can I connect that to a serial port on an old PC?
That jog wheel is beautiful, maybe Mame mouse ready? Keyboard could act as the fire buttons.
Actually, you can just push down the jog wheel to act as mouse click. Unfortunately, there's no right-click. You can command-click on a mac.
There have been some strange interfaces going the serial/parallel route such as Disney's Sound Source and the N64-PSX Dex drives memory backup. So it is possible, but since most spinner games utilize a mouse not practical. A mod of a ball mouse might be the easiest solution for compatibility.
I was hoping that someone had already written a windows serial driver compatible with atari controllers. It's just wishful thinking I suppose.
