Up to 8x 32Mbit ROMs (27C322) can be used for a maximum of 256Mbit C ROM.  27C800/27C160 can also be used depending on jumper config. Size of largest ROM is selected using a pair of jumpers.  The rest should be left unconnected.

A [[NEO-273]] and a LS74 are used to address C ROM.  LS74 provides the 2 most significant bits. LS139 enables one of four pairs of C ROMs using 2 address inputs depending on which 2 jumpers are connected.
