PREFACE
Coke vending machines are everywhere. They're getting more and more like regular computers with LEDs that show little "ICE COLD" messages and whatnot. Well, there's a lot more to those little built-in computers than you may think. Included in the low-level operating system that these babies run on is an actual debug menu that gives you access to all sorts of machine information and possibly gives you free cokes in older machines.
WHICH MACHINES WORK?
There's a very strict list of vending machines that have the debug menu. First off, they're all COCA-COLA product vending machines. This means the giant, un-missable picture on the front must show any of the following: Coke, Dasani (Water), Barq's Root Beer, Vanilla Coke, Cherry Coke, Sprite, Evlan (water), Fanta, Fresca, Frutopia, Hi-C, Sprite Remix, Mad River, Mello Yello, Minute Maid, Nestea, Odwalla, Mr. Pibb/Pibb Xtra, Planet Java, Power Ade, Seagram's Ginger Ale, Simply Orange, Sparkletts, or Tab. Of course anything Diet or Caffeine free works too.
The machine must have an LED screen. Some of the older ones just allow the LED to be set to a price amount and won't have the debug menu. You're safer if the little LED is telling you something. Usually it will scroll a little message like "Ice Cold Cokes". Newer machines are more likely candidates.
ACCESSING THE MENU
To enter the menu, there's a button combination. HERE'S THE ONLY THING YOU HAVE TO REALLY REMEMBER:
[4]-[2]-[3]-[1]
The buttons are numbered depending on how they are positioned. They will either be vertical (more likely), or in horizontal rows of 4 buttons per row. If it is vertical, the first button is #1, the one below it is #2, and so forth. If the buttons are in horizontal rows, the first button is #1, and the one to the right of it is #2. The numbers work like a type writer after that. In rows of 4, the first button of row 2 will be button #5. So, to review, getting in to the debug menu looks like this:
COKE MACHINE::::::
$1.00 -------
-------------
[ Coke ] <-- Hit this button last
[ Coke ] <-- Hit this button second
[ Diet Coke ] <-- Hit this button third
[ Sprite ] <-- Hit this button first
[ And so on ]
-------------
Some text should show up on the LED (probably the word "Error", we'll explain what it means next sections). If nothing happens, your machine doesn't have the debug menu.
NAVIGATION
To navigate from option to option (What they are is next section), remember the numberings we gave the buttons. They work as follows:
Button [ 1 ] - Exit/Back
Button [ 2 ] - Up
Button [ 3 ] - Down
Button [ 4 ] - Select
OPTIONS
Depending on the age of the machine, you will get a varying amount of options.
On older machines: SALE, VER, EROR, and RTN
On newer machines: CASH, SALE, EROR, and RTN
-CASH
The CASH option will display how much money is in the machine currently. It generally takes a second or two to load. From here, you can scroll up and down through 12 or 16 different options, depending on the machine age. These other options display how much money was spent on each individual item, classified through its button (or slot, as I like to call it) number.
A neat side note about the slot numbers is that there are more slot numbers than there are actual slot, so usually the last 4 buttons contain zero money. This could be so that the same OS could be used on bigger machines, but the newer machines have even more slot numbers.
-SALE
The SALE option displays how many drinks have been sold out of the machine. This tends to be cumulative, but not on all machines. The stock guy is probably supposed to reset this each time he re-stocks. Also, this has the same sub-options as the CASH option, where you can scroll up and down and see how many drinks have been sold from each slot.
-VER
This option will cause a large alphanumeric string to scroll across the LCD. The number looks very much like a serial number, but doesn't vary from machine to machine. It is most likely the OS or machine version number, but of the older machines that have the option, I haven't seen one that doesn't have the same number.
-EROR
The most mysterious of the options, the EROR function will usually display the word "NONE" across the LCD. Almost all machines show NONE, but we came across one old one by a Food Lion that actually said something. This is an error log. If an internal error occurs, it will list it. So far, I know of "DOOR" and "STS" errors. If you get an error, you can select it, and it will clarify which part exactly had a problem, as in "STS002" or "STS005".
-RTN
This is simply the return option. Selecting this will exit the debug menu. On newer machines, pressing the BACK button at the main menu will not exit, and RTN must be selected.
A side note: The menu can also be exited by pressing the coin return button.
EXTRAS
By holding in the coin return button and not releasing, on the newer "big-button" machines, this will display the internal temperature in Fahrenheit, as in "42F".
USEFULNESS
This is of absolutely no use, as there is NO way to gain free drinks or money from this. "

This is of absolutely no use, as there is NO way to gain free drinks or money from this. "
The last part "There is absolutly no way to gain free drinks". Is mostly wrong, There is a way but 1 that would be completely illegal, and 2 if you want to risk it go to one of those sites like I-hack.com or astalavista.com. But I suggest not trying to do it. (The way isn't completly free, but you can change prices of the soda)
It works just fine for me. You can also see how man have been sold in the past month. And you can ghange the LED message
