The Heavy Sixer is the nickname
given by Atari
collectors to the original Atari 2600
model which was mainly produced in 1977
in Sunnyvale, California
, though some later units were constructed in Taiwan
when production was moved overseas. Sears
series of Atari 2600
clones were also produced in the Heavy Sixer variety.
They receive the nickname
"Heavy Sixer" due to the fact that there are six chrome
switches on the front of the unit, and there is heavy internal RF shielding
which makes it noticeably heavier than the later run of CX2600
models produced in 1978
. The plastic molding on the sides and front of the unit is also thicker than that of later models.
Needless to say, the Heavy Sixer is more uncommon than other Atari 2600
units and is highly sought after by collectors.
