There are also ram expansion accessories that connect to the system bus and either add extra banks of 32k to the internal ram, or replace the internal ram. These aren't normal ram modules that plug into the normal ram sockets. They plug in to the system bus connector and provide the entire 32K address space at once from there, as if all ram sockets were filled.
