What I’d really like to see is an emulator for AS/400 on mainstream hardware. QEMU supports PPC emulation for AIX, but RISC OS/400 needs some extra features it doesn’t emulate, and I don’t know if anybody has ever built an emulator for the CISC platform (probably IBM had one internally at some point, but I doubt any of their internal bits will ever see the light of day)
