These are the first released models of the Atari 2600. The name "Heavy Sixer" is due to the fact that these consoles have a thick styrene bottom case, which adds considerable weight to the console. Most "Heavy Sixers" were produced in Sunnyvale, California, close by Atari's headquarters. Due to their short production run, these consoles are somewhat difficult to find. There are some claims that these consoles possess a superior color saturation in the video output, but this claim is completely unverified and needs to be properly tested. | [[File:Atari-2600-Heavy-Sixer-2K.jpg|200px|thumb|rigt|Atari 2600 VCS 6 Switch "Heavy Sixer"]]These are the first released models of the Atari 2600.

Perhaps one of the most unique variations of the 2600 hardware, this console was initially released in the US as the "Sears Video Arcade II" in late 1982, and in Japan as the "Atari 2800" in 1983. This console features a sleek and relatively small case, which was later reworked for the Atari 7800. On the top of the console are the difficulty switches, Select, Reset and two buttons which switch the controller ports into either joystick or paddle mode. These latter two buttons are present because the console came bundled with unique controllers which combined the joystick and paddle controllers into a single unit. Because of this, the Video Arcade II/2800 is the only 2600 variant to have four controller ports. All four ports are located at the front edge, as is the power switch. | Perhaps one of the most unique variations of the 2600 hardware, this console was initially released in the US as the "Sears Video Arcade II" in late 1982, and in Japan as the "Atari 2800" in 1983.

The final variation of the 2600 hardware, originally released in Europe in 1984 and the rest of the world in 1986. Though still officially branded as the "Atari 2600", this model is colloquially known as the "2600 Jr." due to its small form factor. Functionality is the same as the four-switch models, but the design has been significantly overhauled to be smaller, thinner, and with a distinctive faceplate in the center, usually made of aluminum. | [[File:Atari-2600-Jr-FL-2K.jpg|200px|thumb|right|Atari 2600 Jr]]The final variation of the 2600 hardware, originally released in Europe in 1984 and the rest of the world in 1986.

The Jr. models tend to have poorer reliability, as Atari switched to using a mylar flex circuit for the Select and Reset buttons. This flex circuit tends to become oxidized and non-responsive, and will require outright replacement or modification of the console to use tact switches for these functions. | The Jr. models tend to have poorer reliability, as Atari switched to using a mylar flex circuit for the Select and Reset buttons.

Some later 2600 Jr. models also feature a cost-reduced chipset, with all three major chips (6507, TIA and RIOT) being consolidated into a single ASIC. This ASIC is known as the RP2A10 and was manufactured by Ricoh for Atari. These particular variants are highly difficult to find and are externally indistinguishable from other 2600 Jrs.

Revision as of 19:30, 4 December 2022
Some page content & researching collaboratively taken from io55.net's Atari 2600 page with permission.
There are four 2600 models, and five revisions within three of these models.
Models + Revisions
Models are arranged chronologically. Revisions are underneath their respective model.
Six Switch / Woody (1977-1981)
Branded as the "Video Computer System", these systems possess six switches on the top of the console and have an internal two-piece construction, with the switches, RF modulator and power circuitry residing on a separate board from the main board, the latter of which is housed in thick RF shielding. Both Atari and Sears-branded models exist for all six-switch consoles, with the Sears model being known as the "Sears Video Arcade". These are identical to their Atari-branded counterparts and were made on the same assembly lines, but have a different false woodgrain pattern and a silver inlay surrounding the cartridge port and switches.
"Heavy Sixer" CX2600 (1977-1978)
These are the first released models of the Atari 2600. The name "Heavy Sixer" is due to the fact that these consoles have a thick styrene bottom case, which adds considerable weight to the console. Most "Heavy Sixers" were produced in Sunnyvale, California, close by Atari's headquarters. Due to their short production run, these consoles are somewhat difficult to find. There are some claims that these consoles possess a superior color saturation in the video output, but this claim is completely unverified and needs to be properly tested.
“Light Sixer” CX2600 (1978-1981)
These make up the vast majority of six-switch Atari 2600s. Aside from minor board revisions, the only significant difference between these models and the "Heavy Sixer" is that they have a thinner, angled ABS bottom case, a change made to reduce production costs. Early "Light Sixers" were manufactured in Sunnyvale though most were made overseas in Taiwan and Hong Kong. They are easier to find than the “Heavy Sixer”, while offering zero feature sacrifice and minor reliability sacrifice.
Four Switch (1981-1985)
The first major revision to the Atari 2600 since its introduction. In an effort to further reduce production costs, the entire console was consolidated to a single PCB with thin RF shielding, as opposed to the six-switch's two-piece construction and thick shielding. The most notable external difference is that the difficulty switches were reduced to simple plastic slide switches and relocated to the rear of the console.
There are minor motherboard revisions for both four-switch variants, with the maximum extent being the addition of a timer chip in later board revisions, which eliminates the minor issue of reset failures upon powering on the console.
CX2600A (1981-1982)
One of the most common 2600 variants as it was sold during the system's height of popularity. This variant still features the same false wood grain trim as on the six-switch consoles. This was the last version of the 2600 to be sold as a Sears variant.
Atari 2600 (1982-1985)
Commonly known as the “Darth Vader” model, due to its all-black appearance and lack of wood grain. Atari also officially rebranded the system as the "Atari 2600" with this variant, attempting to give the console a family look with the recently released Atari 5200. Outside of this visual difference, the "Vader" models are largely identical to the previous wood grain variant. Despite a corporate switchover during 1984, these continued to be manufactured into 1985.
Sears Tele-Games Video Arcade (1977 - 1983)
Sears rebranded the "Light Sixer" and 4 switch "Woody" models under the Tele-Games Video Arcade system internally they are the same just with different branding and wood decor. After 1983 and the North American home video game crash
Sears switched to selling Atari branded consoles, as well as Coleco's clone console the Gemini.
Sears Video Arcade II/Atari 2800 (1982, 1983)
Perhaps one of the most unique variations of the 2600 hardware, this console was initially released in the US as the "Sears Video Arcade II" in late 1982, and in Japan as the "Atari 2800" in 1983. This console features a sleek and relatively small case, which was later reworked for the Atari 7800. On the top of the console are the difficulty switches, Select, Reset and two buttons which switch the controller ports into either joystick or paddle mode. These latter two buttons are present because the console came bundled with unique controllers which combined the joystick and paddle controllers into a single unit. Because of this, the Video Arcade II/2800 is the only 2600 variant to have four controller ports. All four ports are located at the front edge, as is the power switch.
On the rear is a barrel jack for power, making the SVA II/2800 the only official 2600 variant to have such a connector (all others use a 3.5 mm mono jack). It is designed to accept a 9V AC power supply, but a DC power supply with sufficient voltage and current (9-12V DC, >500 mA) will work as well. As with most other 2600s, the RF cable is hardwired (but is connected to an internal RCA jack) and can be stored in a cable wrap molded into the bottom of the lower case. Both the channel select and B&W/color switches are also located on the bottom.
Both the Sears Video Arcade II and Atari 2800 are almost completely identical, with the only differences being the nameplate on the console and the RF modulators being tuned for their respective countries. Sears consoles were manufactured in Sunnyvale while 2800s were manufactured in Hong Kong.
2600 Jr. (1984-1992)
The final variation of the 2600 hardware, originally released in Europe in 1984 and the rest of the world in 1986. Though still officially branded as the "Atari 2600", this model is colloquially known as the "2600 Jr." due to its small form factor. Functionality is the same as the four-switch models, but the design has been significantly overhauled to be smaller, thinner, and with a distinctive faceplate in the center, usually made of aluminum.
The Jr. models tend to have poorer reliability, as Atari switched to using a mylar flex circuit for the Select and Reset buttons. This flex circuit tends to become oxidized and non-responsive, and will require outright replacement or modification of the console to use tact switches for these functions.
An early all-black variant exists, but its changes are entirely cosmetic. These all-black models were manufactured in Ireland and only sold in Europe.
"Unicorn" variant (1988-1989)
Some later 2600 Jr. models also feature a cost-reduced chipset, with all three major chips (6507, TIA and RIOT) being consolidated into a single ASIC. This ASIC is known as the RP2A10 and was manufactured by Ricoh for Atari. These particular variants are highly difficult to find and are externally indistinguishable from other 2600 Jrs. Due to its rarity, it is commonly referred to as the "Unicorn" model.
Coleco Gemeni (1983)
Coleco a new upstart in the video game market not only released their own console the Colecovision they reverse engineered the Atari 2600 and released their own clone console that was competing with the 2600 and marketed as compatible with the 2600's library of games. It is design wise completely different from all Atari versions with front facing controller ports and difficulty switches and four switches on the top of the system and an off center cartridge slot. This was the product of reverse engineering the Atari 2600 hardware, and Coleco was later sued but won it's case against Atari and was allowed to sell it's system.
