Firstly, the controllers have been made detachable, and now resemble the typical gamepad of the era. The distinctive blue stripe has been removed, and Sega Cards are now supported through an adapter. Lastly, a keyboard addon is now available through the front, making the II closer to the SC-3000.

There is one revision within the SC-3000, and no revisions for the other two.

A premium version of the SC-3000, which has mechanical keys, instead of the chiclet keys seen on normal SC-3000s.
