Title: Need pinouts for Atari (Tempest) Coin Door Harness
Post by: t3design on August 13, 2011, 05:55:55 pm
As the topic says, I have an original coin door from an Atari Tempest machine. I would like to leave it intact and use in my Cowboy Arcade. I am hoping someone has the pinout diagram for the 24 pin male molex connector on this harness.

Thanks!!!

OK, I borrowed a multi-meter and traced down all the pins:

1   Center Coin Switch
2   Right Coin Switch
3   Left Coin Switch
4   Reset ON & Momentary Switch
5   "Tilt" Switch
6   Switch Common (Coin, Reset, Tilt)
7   Solenoid Common
8   Center Solenoid
9   Right Solenoid
10   Left Solenoid
11   Extra Counter A1
12   Extra Counter A2
13   Top Counter 1
14   Top Counter 2
15   Bottom Counter 1
16   Bottom Couter 2
17   Extra Counter B1
18   Extra Counter B2
19   Coin Return Lights Power
20   Coin Return Lights GND
21   Not Used
22   Not Used
23   Chassis GND
24   Chassis GND

Now I have a different question.

The Counters operate on 6VDC (I got them to actuate on 5VDC). It does not matter which way you apply power. While it is hard to folow the wiring in the harness, it is obvious that the coin switches are not connected to the counters in any way on the door. So, was there hardware that sent back a 6VDC signal when the board detected a coin drop to increment the counter? Is there any reason I can't just use a pretimed solenoid to provide a short pulse each time the coin switch contact closes?

FYI you can download the Tempest manual and schematics from KLOV:
