The new version of RISC OS, the original native Arm OS, runs on eight or nine Arm-based platforms, including the Raspberry Pi Zero, 1, 2, 3 and 4 – and on that last two, this release supports wireless networking.
RISC OS 5.30 is the latest release of Acorn’s original native operating system for its Arm processors.
This is a fairly modernized and refurbished late-1980s single-user GUI-based OS, and that implies some limitations. It was first released the same year as OS/2 1.0, long before Apple System 7 or Windows 3.0. In fact, it’ll remind you of Windows 3 on MS-DOS: it’s a single-tasking text-mode OS, with networking, on top of which is a graphical desktop that does cooperative multitasking.
But saying that, it’s an admirably complete OS, in this vulture’s opinion, with quite a rich portfolio of applications. RISC OS 5.30 comes with a selection of productivity apps, plus development tools, including a choice of editors, Python, Lua, and a C compiler – and of course with a 32-bit version of BBC BASIC V, a fully structured interpreter which also supports inline Arm assembly language.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
