Setting up an older #RISC_OS 5 system as a freebie for a returning user. It's amazing what you forget: How slow SD card storage is; How fast a Pi 3B+ was in its day; How cool it runs! It's a good little machine, but it does remind you how far we've come since then.

Got a couple of weeks gap between jobs so caught up on some #RISC_OS programming. Can now drag a folder to an icon and display a basic tree view. Can load and save text files and already had a basic layout manager. Time to start building a text editor...
