Controller types 32 and above were added by RISCOS Ltd and are currently only supported by their versions of the OS.
Although controller type 33 is currently unsupported by RISC OS 5, the IOMD address can be determined by reading the SSpace address instead, as IOMD is located at the base of SSpace.
