Yep, I think of Arthur as a sortof Beta for RiscOS
I had an Archimedes A305 which launched with Arthur, when I upgraded to Risc OS (which arrived on ROMs, if I remember correctly, you ordered the ROMs and then your local dealer would fit them onto the motherboard) it wasn't really _that_ different, everything I'd written continued to work, etc. Like it was a major upgrade but fundamentally the same "thing".
I had that same model, except I fitted the chips myself. The first time I’d really ever looked inside a computer and very exciting for me age 11. The old Arthur ROMs were a prize possession for quite some time afterwards.
