ITS ALIVEEEEE! (Ish) so the seller did a terrific job of mummifying this beauty in enough bubblewrap to get here safely. It smells very much of being in a shed but after leaving it 2 days to dry I powered it up and here we are!

Here's a brilliant book for anyone who has an interest in Acorn Computers, The BBC Micro, ARM or technology in the UK around that time. A collection of stories by the people who made it all happen. Whilst I have only quickly skimmed the contents since it arrived today, I know it's a 10 out of 10!

New arrival and straight to the top of my to read list. Review to follow, hopefully before the RISC OS North Show in a couple of weeks!

The RISC OS North show should be fun.

I've often wondered what a decent Gnome-type dark theme might look like on RISC OS.

Is it time for a Spring 🌱 theme?
