The Commodore/Unicomal Comal 80 cartridge does: It comes with two 27256 pin compatible ROM chips, and there is an empty socket that allows for an extra, user installed 27128 or 27256 EPROM (jumper option). The banking scheme would allow for 32k more to give 128k total cartridge ROM space. With a little modification it would of course be possible to install a 27512 user EPROM that fills up all of the remaining space. I think I know how the banking register works, I was able to dump all ROM banks to disk. There's an extra bit that controls GAME and EXROM, but that's all there seems to be in this cart.
