MEMORY CONFIGURATION

The memory sockets U1 - U16 on this card accept SRAM chips (581000 or 584000), EPROM chips (27010, 27C020, 27C040, 27C080, or 27C301), and Flash EPROM chips (28F010, 28F020, 29F010, or 29F040). The sockets can be filled in any order and SRAM chips can be mixed with EPROMs. Only one size of each type of chip installed may be used (i.e. all EPROM are 27C080 chips and all SRAM are 581000 chips).
