4.5" Atari Trackballs (Missile Command, Atari Football)
These giant trackballs are sometimes known as 4-inch, but are actually 4 and a half inches in diameter. They were some of the first trackballs put into use, and are designed to survive intense abuse.
Happs sells a 4.5" trackball. The ball itself is usable in an Atari 4.5" (a 4.5" diameter sphere is a 4.5" diameter sphere), but the mechanism itself is a different, less industrial design.
Any 4.5" diameter ball, particularly a candle-pin and/or duck-pin bowling ball, is a swap-out replacement for the 25+ year old originals.
The original optical boards on these are fairly easy to interface with an Opti-PAC (and therefore most other optical control interfaces). This is the pin-out for the 10-pin molex plug found on the optical boards:
| 1 | no signal |
| 2 | no signal |
| 3 | no signal |
| 4 | X1 or Y1 |
| 5 | no signal |
| 6 | no signal |
| 7 | no signal |
| 8 | X2 or Y2 |
| 9 | +5v |
| 10 | ground |
On an optipac the "A/HI" jumper should be set.
There were a number of different boards with this same pin-out.
There are a number of places that sell replacement bearings and roller-shafts for these, they are often referred to as 4" trackball rollers.
