The Mega Drive/Genesis is the obvious answer, but I can also make a case for the earlier Master System. Initial models were fully compatible with Sega's prior console, the somewhat obscure SG-1000.

Noone wants to buy a machine without games, and noone wants to upgrade and lose the ability to play old games. Note like console makers have a "all or nothing" way of handling the compability.
