RiscCAD is an advanced 2D CAD application for the RISC OS operating system. This operating system was initially developed for Acorn Computers for their range of 32 bit RISC desktop computers (Archimedes and RiscPC). RISC OS can now also be run on PC and Apple computers using an emulator from VirtualAcorn. RISC OS is also available for other small ARM based micro processor boards such as the RaspberryPi.
