How odd. This is the second time _this evening_ that this false information has come up. No, it was not written in BASIC. Arthur *the OS* was hand-coded in Arm assembly language, including the BBC BASIC V interpreter. The GUI, in Arthur called DESKTOP, was written in BASIC. Just the desktop, nothing else. Later called the WIMP, and still around today and open source. I wrote about it: version 5.30 just came out, runs on bare metal on 7 different Arm boards, and on the Raspberry Pi this version supports Wifi for the first time. https://www.theregister.com/2024/05/02/rool_530_is_here/ -- Liam Proven ~ Profile: https://about.me/liamproven Email: lpro...@cix.co.uk ~ gMail/gTalk/FB: lpro...@gmail.com Twitter/LinkedIn: lproven ~ Skype: liamproven IoM: (+44) 7624 277612: UK: (+44) 7939-087884 Czech [+ WhatsApp/Telegram/Signal]: (+420) 702-829-053
