Welcome to APDL and iSV Products

Software and Hardware for RISC OS and Acorn computer systems

APDL supplies software and hardware for RISC OS (formerly Acorn) computer systems. Although some items may be usable on a PC or Apple Macs we do not directly support anything other than RISC OS.

Subscribers to RISC World magazine can now claim a 10% discount on most APDL, APDL-ProAction or iSV Products software titles.

APDL and ProAction have now taken over The Fourth Dimension. This means we have added a huge number of games titles to our software catalogue. We shall shortly be announcing availability and pricing of these, and also a number of compilation CDs.

RISC OS is a proprietory operating system which runs on RISC processors designed by ARM Ltd. You can't run any of our software on a Windows PC unless you are running an emulator (see below).
