Sideways address space and BBC Master all featured Sideways RAM as standard. The machines used the 8-bit 6502 and 65C102 processors with a 16-bit address space. The address space was split into 32 KiB RAM (0x0000 to 0x7FFF), 16 KiB Sideways address space (0x8000 to 0xBFFF) and 16 KiB operating system space (0xC000 to 0xFFFF).

On both the BBC Micro and the BBC Master, there are ROM sockets on the
