Throughout the remainder of this manual, the generic

reference to a specific model is required.
This manual supplements the basic information given on

Reference Manual (available for separate purchase).
The operating systems, RISC OS and RISC iX, are
covered at the user level in the RISC OS User Guide and
the RISC iX User Guide, supplied with certain models (

They are available from Acorn authorised dealers. Full
