Archimedes Arthur Programmer's Reference Manual

The Archimedes Arthur Programmer's Reference Manual provided vital information on how to create programs for the Archimedes range of computers. This edition covered the original Arthur OS and was superseded by the RISC OS 2 and then RISC OS 3 Programmers Reference Manual when the operating system was upgraded from Arthur and RISC OS 2 to RISC OS 3 respectively.
