Programmer's Reference Manuals

The RISC OS 5 Programmers Reference Manuals, commonly known as PRMs, are in the process of being made available online. The RISC OS 3 PRMs in PDF form is freely available here. A collection of "PRM-like unformation" is also available on Robin Watts’s Pink Noise Productions website.
