PRINTED CIRCUIT BOARDS --------------------------------------------------------------------------------------------------------------------------------------
The NES is actually a computer, with some swappable hardware (the game cartridges). As mentioned on the Cartridge Design page, each game consists of a printed circuit board, or PCB, in a plastic case. When talking about an NES game, a PCB can best be described as a piece of plastic that is embedded with lots of copper highways and connectors that move data between whatever integrated circuit (IC) chips have been attached to it, and the NES console. Some games are more complicated than others and therefore require more IC chips (and larger PCB's) to make them work correctly. Fortunately for Nintendo, the game cartridges were much larger than the PCB's required for the first games, which allowed for games to get bigger and better as time went on.

COMPONENTS ------------------------------------------------------------------------------------------------------------------------------------------------------
To illustrate the basic parts of an NES PCB I'm going to use a model NES-SNROM taken from my original copy of The Legend of Zelda that I've had since I was a kid. Some PCB's do not have all of these components, and some have more. The ones with more IC chips are just adding more memory, not new functionality, so this game is a good example to use.

Notice that the model number of this specific PCB has a "-04" at the end of it. This indicates the 4th incarnation, or revision, of this particular PCB (not of the game loaded onto it). The same PCB's and chips were used for multiple different games, and Nintendo bought IC chips and batteries in bulk from lots of different manufacturers. So not only can the same PCB build go into different games, but different copies of the same game can be made up of parts from different sources from one production run to the next. In this case the WRAM is from Panasonic, the Character ROM is from NEC, etc.
​
Some games were produced on more than one PCB model. For example, Goal! uses model NES-SLROM, but there are also copies that exist with the model NES-SL3ROM. It's the same exact game, just built onto a different PCB.

The multi-game carts that came with the NES consoles were frequently manufactured with a Chip On Board (COB) or "Gel Blob" PCB. Unlike the IC chips in cases that solder into a socket, the chips on a Gel Blob PCB are glued directly to the board and connected with microscopic wires, then covered with the protective blob. These are cheaper to make for games that don't require much hardware, and are a useful alternative if there's a chip shortage, which there supposedly was at the height of the NES era. Some copies of the multi-game carts will have standard PCB's, but they can be tough to find.

Some games by Milton Bradley, Konami/Ultra, and Acclaim/LJN will have a PCB made out of varying shades of blue plastic instead of the traditional green. There is nothing different about the boards or the games, just the color.

ROM & RAM ---------------------------------------------------------------------------------------------------------------------------------------------------------
To understand what each component actually does, it is necessary to know the difference between ROM and RAM. ROM stands for Read Only Memory, meaning that ROM chips store information that cannot be changed or deleted. Data is read off of these chips, and that's it. RAM stands for Random Access Memory, meaning that the chip will temporarily store data, but is empty by default. Data is moved into the RAM chip's memory as needed, and is later automatically deleted once it's no longer in use, or the power is turned off.

Lockout Chip
This chip stores the actual game software, the code that is the game itself.
​
This chip stores all of the graphics for the game.
​
The WRAM chip in the NES console is where the live version of the game exists as you are playing it. As games got more sophisticated they required more WRAM than the console had to offer, so WRAM chips were added to the PCB's to compensate.
The technical name of this chip is Memory Management Controller (MMC). The mapper acts like a switchboard between the PCB and the NES console's CPU, allowing access to more lanes of data than the console's hardware could handle by itself, and therefore higher-quality and more complex games.
​
The battery effectively keeps the power turned on after you turn the console off, which holds your current game state in the WRAM chip until you play again. They are always lithium-ion, model CR-2032. Not all PCB's that have a space for the battery actually have one, as some games will use that model PCB but do not require a battery. Anyone working on solving the world energy crisis should really be studying the exact chemical composition of the NES batteries because most of them still work after several decades.
​
The technical name of this chip is Custom Integrated Circuit (CIC). This chip communicates with another lockout chip in the NES console that runs a program called 10NES. If a game cartridge doesn't pass the 10NES verification on startup, the console goes into an infinite reset mode (the infamous blinking red light). This was a quality-control measure Nintendo put in place to stop piracy and to deter the development of unlicensed games. Ironically the lockout chips would sometimes become glitchy and cause problems. Think your NES console is broken because it won't load the games most of the time and just keeps resetting no matter how much you clean it? Try disabling the lockout chip in the console by cutting pin number 4. Just please don't hold me responsible if it still doesn't work and/or you ruin your NES. A lot of the unlicensed games that were made to be played on the NES defeated the lockout chip by sending a high voltage spike on startup that would essentially crash the 10NES program and prevent the never-ending reset. Therefore, some unlicensed games require the lockout chip to be present or they run the risk of overheating the console. The Aladdin Deck Enhancer from Camerica was notorious for destroying the top-loader NES-101 console for this reason. Top-loader's don't have lockout chips. It was cheaper to leave them out, and by the time this model was released nobody was developing new unlicensed NES games anymore.

Just like the the PCB's in the games, the NES console's motherboard is a PCB with a model number and revision number on it. The model number of the NES console motherboard is NES-CPU-xx, where the last 2 digits are the revision number. As time went on Nintendo added more security to the board to defend against lockout chip attacks, and unlicensed games that worked on older consoles would not work on newer ones. The last revision of the NES console was NES-CPU-11.

This notecard was included with games sold by unlicensed manufacturer Camerica. If you didn't know any better you'd think it was giving you tips on how to make your unreliable NES console work, but what it's really doing is telling you how to wage war on the 10NES lockout program and make their unlicensed game cartridge work by crashing the system.
This warning sticker was placed on the packaging of some unlicensed games from American Video Entertainment. It alludes to Nintendo upgrading its Lockout Chip technology over time to combat previously successful attempts by unlicensed manufacturers to bypass it.
DATE CODES -------------------------------------------------------------------------------------------------------------------------------------------------------
Depending on the manufacturer, the IC chips have lots of different data stamped on them that ultimately identifies 3 things - The ROM label (what's on the chip), the part number of the chip itself, and manufacture date. Some manufacturer's codes for this are easy to crack, others are more complicated. The individual IC chips on a PCB will each have their own date code and, while they rarely match exactly, they are usually within a few weeks (sometimes months) of each other.
​
Date codes on IC chips are a computer industry thing, not an NES thing. Every company has its own system, but they all translate into the same formula: Year and week of manufacture. The standard date code consists of four numbers: 2-digit year and 2-digit week (YYWW). For example, the code 8901 translates to the 1st week of 1989, or January 1989. The code 8734 translates to the 34th week of 1987, or August 1987. The standard 4-digit code can almost always be found on the lockout chip, although sometimes they feature a 3-digit YWW code with the letter "C" as a prefix instead. For example, the code C050 would be the 50th week of 1990, or December 1990. See examples below of both styles, representing the exact same date.
​
​
​

​
​
It's worth noting that the dates on the lockout chips start getting unreliable on some games around the end of 1991, sometimes pre-dating the ROM chips by a year or more (see final example below from Tiny Toons 2). It's not a coincidence that this lines up with the release of the Super Nintendo, at which point production of NES games began to quickly decline. The IC chips usually get stamped when their content gets loaded, so while the ROM chips don't get a stamp until the final version of the game is loaded, the CIC chips could have been prepped and ready to go way in advance since they were universal and could be used with any game at any time. If production dropped off when the SNES launched, it's likely that there were lots of CIC chips already stockpiled, or on order, that took a while to use up. The most accurate code for a game's actual build date will always be on the ROM chips, even though they can be harder to read.
​
Translating the 2-digit week into the correct month is not always as easy as it may seem. The dates on the chips use the ISO-8601 week numbering standard where weeks run Monday-Sunday, and the first week of the year must contain the first Thursday. Therefore some years, 1987 and 1992 for the NES era, have 53 weeks. Click here for chart of YYWW.
​
Below are some examples of PCB's with different date code styles, and how to translate them. There are more than this to be found, but these are the most common. Knowing which parts of which codes to focus on is half the battle, so the more of these you translate, the easier it becomes to recognize what you need. Also, some of the more complicated codes get extra-specific about the week of the month, or the actual day. While this is interesting info, it's usually overkill and not relevant when working on a YYWW system where the goal is to simply get a year and month of manufacture.

11th week of 1987, or March 1987.
​
CROM date code 8712:
12th week of 1987, or March 1987.
​
PROM date code 7C2:
This is a year-month-week (YMW) format where the month is a letter A-M ("I" is skipped since it looks just like a "1"). 2nd week of March 1987.
CIC date code 8744:
44th week of 1987, or October 1987.
​
CROM date code 7J:
This is a year-month (YM) format where the month is a letter A-M (skipping "I"). September 1987.
​
PROM date code 8747:
47th week of 1987, or November 1987.

CIC date code 9011:
11th week of 1990, or March 1990.
​
CROM date code 0CB:
This is a year-month-day (YMD) format where the month is a letter A-M (skipping "I"), and the day of the month is a letter A-Z. Since there are more than 26 days in each month, these were probably working days as opposed to calendar days. 2nd day (1st week) of March 1990.
​
PROM date code 0CB:
2nd day (1st week) of March 1990.
CIC date code 8944:
44th week of 1989, or November 1989.
​
CROM date code 9J:
This is a another example of a year-month (YM) format. September 1989.
​
PROM date code 9K1:
Note that this is the same chip as the PCB above, just from the previous year. This one is another year-month-week (YMW) format. 1st week of October 1989.

Mickey Mousecapade
CIC date code 9009:
9th week of 1990, or March 1990.
​
CROM date code 059:
This one is weird. The code is year-month-day (YMD) format with a symbol attached to the month digit to indicate the day. If the month has a line above it, that indicates the 1st third (or 10 days) of the month, so the day would be the the day digit +1. If there is no line, that indicates the 2nd third of the month, so the day would be the day digit +11. If the month has a line under it, that indicates the 3rd third of the month, so the day would be the day digit +21. Adding to the confusion, January-September are numerical 1-9, but October is O, November is N, and December is D. May 10, 1990.
​
PROM date code 047:
Same as above. April 28, 1990.
CIC date code 8824:
24th week of 1988, or June 1990.
​
CROM date code 85:
This is a simple year-month (YM) code, but with a twist. The month digit is a number 1-9 for January-September. But October-December would be represented as a letter, either A-C, J-L, or X-Z. May 1988.
​
PROM date code 8819:
19th week of 1988, or May 1988.
CIC date code 8956:
56th week of 1989??? It's not too uncommon to see a chip like this where the manufacturer apparently made a mistake. My guess is that this was supposed to be 8946 (Nov 1989), which would align with the other chips.
​
CROM date code 941:
This is a simple YWW code. 41st week of 1989, or October 1989.
​
PROM date code 9L4:
Same YMW format as previous examples. 4th week of November 1989.
WRAM date code 9Y:
This is an example of the YM format described on the CROM chip above, but with October-December being represented by X-Z. November 1989.
CIC date code C139:
39th week of 1991, or September 1991.
​
CROM date code 2AC:
This is another YMD format. January 3, 1992.
​
PROM date code 2AC:
January 3, 1992.
WRAM date code 136:
This is an example YWW format. 36th week of 1991, or September 1991.
CIC date code 9142:
42nd week of 1991, or October 1991.
​
CROM date code 9309:
9th week of 1993, or March 1993.
​
PROM date code 9309:
9th week of 1993, or March 1993.

PCB MODELS --------------------------------------------------------------------------------------------------------------------------------------------------------
Below are examples of each PCB model and a listing of which games they were used for. Toward the end of the NES era, Acclaim (and their subsidiary LJN), Konami (and their subsidiary Ultra Games), and Virgin Games manufactured their own PCB's. When these PCB's do not have model numbers printed on them, they are named here after their NES counterparts that were used on the same games. In cases where there is no NES counterpart PCB, the model is taken from the manufacturer-branded IC chip on the board.
