Um, misnomer here. The language as such was a binary file that was
loaded onto that card, when booting an appropriately configured DOS3.3
Master disk on an appropriately configured Apple 2Plus. Such
configurations presuppose that the computer left the builders wearing
48K of memory and expected 16K on that card who went into the Zero

Given the rest of the board is just TTL support logic and bus transceivers, and there is no ROM present, I don't think it can be called the "language card" which traditionally provided both the 16K and full featured BASIC. That RAM chip in the bottom right (with the apple logo) is likely from the Apple II mainboard itself, which is removed to make a place for the ribbon cable to connect. That socket on the expansion board was likely empty from the factory. That chip could move back to the mainboard, removing the ribbon cable, and that would return the machine to its (likely) original stock 48k configuration.

It has a connector that plugs into one of the RAM sockets on the main board, so I assume it to be a RAM expansion, particularly since it’s populated by 8x16K RAM chips.
