Yeah, the first time I put the control panel top down on the box, it actually bent about 3 of the teeth on the spinner. So much that it would not spin, as the teeth would hit the pickups. I was stressing a little, because that spinner is such a good quality device, an there I was bending it before it was even used. I straightened it back out and it seems to be OK. Also, I noticed if I spin it really fast, the software can't keep up (or the pickups on the spinner, I don't know which). It sure makes playing Tempest just like the old days. Arkanoid works well with the Vortex also. I didn't really need to buy the Ipac 4 since I only have a two player panel. I had this misconception that more is better, but now I have all those waisted terminals for player 3 and 4. Maybe I'll build a 4 player some day. Saint's design has a reset, pause, escape, and two flipper buttons, and I haven't figured out which terminal to wire those to. It seems I will have to reprogram the Ipac also, to add these auxiliary buttons. Any ideas on which terminal to put these buttons?
