At least my own SXs have an 28pin EPROM socket for a 2564 type EPROM. I 
don't think a 24pin ROM with above part number was ever made. Of course, 
2564 EPROMs are also quite rare, but maybe not as rare as the Motorola 
MCM68764/MCM68766 24pin EPROM.

BTW, for those who didn't find this yet, here are some MCM68766 for sale now:
