The TurboTwist 2 did 3 different things in different configurations. I tested in Tempest.
In USB/Legacy mode it worked but wouldn't track at "Normal" playing speeds. You could move the gun, but if you tried moving it at what you thought to be regular playing speed it would jump all over the place. I tried all of the mouse drivers on that page plus a newer one I have on disk from MS. I tried slowing it down with various parameters, it just wouldn't work.
In PS/2 mode it recognized the drive and the device in some drivers but when playing the game it jumped all around and randomly shot (I think it played better than me). I tried a TON of drivers, nothing worked.
In PS/2 mode with some other drivers, it locked up the system if it was attached. It was a pretty nasty lock-up as well. Nothing on the screen, CTRL-ALT-DEL not working. Power down only.
I'm returning the spinner. Incidentally, GroovyGameGear were helpful in trying to help me get it going. They made suggestions and shared what another DOS user had told them. We think it might be the Z-Interface built into the control board. DOS drivers might be confused by it.
I had another issue that was a little weird when testing the mouse drivers. The MAME.CFG file got written as directory entries within the folder I was using for a mouse. When you did a DIR, you saw partial MAME.CFG entries. Weird. I fixed it by installing a different hard drive and reloading. This wasn't entirely a bad thing. I was able to get a 2+GB partition this time instead of a 512MB one. I had made a few changes in the BIOS. Now there's no "Test Stuff" on it.
