It's got 4 joysticks, a spinner, a 3" trackball, and no fewer than 33 buttons. Four of those buttons are on the sides of the panel, like pinball paddle controls (a $30 upgrade that I didn't pay for... I'm not a big pinball fan).
Fresh out of the box!
Posing with a PS2 Dualshock for size comparisons.
Ah, the humble beginning of my Arcade machine.
