From the website: &quot;These books were written for 1980s computers such as the ZX Spectrum and BBC Micro. The programs will not run on modern computers.&quot;<p>Not true! They&#x27;ll all run perfectly on RISC OS on the Raspberry Pi, especially easily on RISC OS Pico.<p>I remember several of these books very fondly, it&#x27;s great to see them made available like this. Usborne Books in general are brilliant.
