The initial production of the VCS was made in Sunnyvale during 1977, using thick [[polystyrene]] plastic for the casing as to give the impression of weight from what was mostly an empty shell inside.<ref name="atari fun chp5"/> The initial Sunnyvale batch had also included potential mounts for an internal speaker system on the casing, though the speakers were found to be too expensive to include;  instead sound was routed through the TIA to the connected television.<ref name="atari fun chp5"/> All six console switches were mounted on the front panel. Production of the unit was moved to Taiwan in 1978, where a less thick internal metal shielding was used and thinner plastic was used for the casing, reducing the system's weight. These two versions are commonly referred to as "Heavy Sixers" and "Light Sixers" respectively, referencing the six front switches.<ref>{{Cite web | url = https://www.digitalgamemuseum.org/you-can-judge-a-2600-by-its-cover/ | title = You Can Judge a 2600 By Its Cover | first = Dave | last = Beaudoin | date = May 31, 2016 | access-date = September 11, 2018 | work = Digital Game Museum | archive-date = September 11, 2018 | archive-url = https://web.archive.org/web/20180911225626/https://www.digitalgamemuseum.org/you-can-judge-a-2600-by-its-cover/ | url-status = live }}</ref><ref name="atari fun chp5"/>

In 1980, the difficulty switches were moved to the back of the console, leaving four switches on the front and replacing the previous all lowercase font for the switch labels to fully capitalized wording. Otherwise, these four-switch consoles look nearly identical to the earlier six-switch models. In 1982, to coincide with the release of the Atari 5200, Atari rebranded the console as the "Atari 2600", a name first used on a version of the four-switch model without woodgrain, giving it an all-black appearance. This all-black model is commonly referred to by fans as the "Vader" model, due to its resemblance to [[Darth Vader|the ''Star Wars'' character]] of the same name.
