Castle, the company that sells Iyonix computers with RISCOS, and RISCOS Open have released the first batch of code for RISCOS 5. According to the last link, “The first set of components released by RISC OS Open and Castle comprises of major applications and modules that form part of the backbone of the operating system”:
These include utility CloseUp; desktop applications Paint, Draw and Edit; the RISC OS Filer and Pinboard; CDFS, various CD device drivers and CDFS Filer; the MessageTrans and BASIC modules; and Browse fetchers. The software is written in a mix of BASIC, C and ARM assembler.
Under terms of the license under which the code has been released, development is limited to ARM processors, meaning x86, PPC, and RISCOS fans using other architectures are locked out. For non-ARM users, rox is a very good, easy to use, and RISCOS-like environment (options can be set so it’s very familiar to RISCOS users).
