He's tried a Castle USB podule but that doesn't work.
Anyone tried a Simtec USB Podule on RISC OS 3.1?
I know Unipod has issues with 3.7 so doubt it would work and would be a very expensive option.
There's a couple of issues:
- whether the USB podule supports IOC podule mode (4KiB address space), or whether it uses the RiscPC's EASI podule space (16MiB). I'd have to dig out
a podule to have a look
- whether the software stack works. Before the RISC OS 6 branch (Adjust
etc), the Simtec stack uses PointerV to inject mouse events. That's a RISC
OS 3.5 interface I think. I'm not sure what it does for keyboard.
I think it's probably not going to work.
For a mouse they could try a SmallyMouse.
For keyboard, you need something that uses the KATN keyboard protocol used
by Archimedes machines.
It appears there are adapters from PS/2 to KATN:

and then you could use another adapter from USB to PS/2
Alternatively I think there's some support for serial mice in RISC OS 3.1
