Dodo uses a 32KB SRAM for system memory and a 32KB EEPROM for system firmware. Both chips happen to have the exact same pinout and both are connected identically, therefore only one chip is shown above in the diagram.
|Address||A0 - A14 address lines. Note that the 65C02 has an additional address line because the 65C02 has 64KB total address space. A15 from the processor is connected to the glue logic.|
|Data||D0 - D7 data bus|
|WE||Write enable. Conneced to WR which is generated from the RW signal from the 65C02. See glue logic.|
|OE||Output enable (Read). Connected to RD which is also generated from the RW signal|
|CE||Chip enable. From the RAM this is connected to the RAM chip select. For ROM, it is connected to the ROM chip select. See glue logic.|
|IC Socket||Socket for the EEPROM|
