I have a RiscPC in the shed and a half-repaired A3000. I don't fire them up them often, but both have !Director launching on boot; it is a wonderful program. Thanks!
I went down a rabbit hole a few summers ago and I ended up writing a calculator from scratch in assembly for RISC OS. Interesting experience having GUI routines at the syscall level
32bit ARM remains my absolute favorite instruction set. And yeah, C compiler output was criminal! I wrote products entirely in the BASIC assembler. What a time to grow up!
