Comments
The Apple II was Apple's first complete home computer sold to
the general public. It was truly a computer for the "rest of us."
It was based on Woz's Apple I motherboard, but came complete
in its own case with its own power supply. In order to avoid FCC
regulations involving radio frequencies, the Apple II produced a
composite signal that could be converted to UHF/VHF to hook to
a TV via a third party adapter. To avoid FCC regulations, this
adapter was not available from Apple and not part of the
motherboard's hard-wired architecture. This allowed Apple to
produce a powerful machine without having to cripple the disk
drives or any other peripheral due to the restrictive rules
governing radio signals, which hampered the designs of many of
its competitors including Tandy, Commodore, and Atari.
