I don't think many people realize how far ahead the Archimedes was at the time.

I got to borrow one from school for the entire summer holidays - a friend and I manhandled the beast to my house - and I spent six glorious weeks with it.

I'd love to find one but I expect they're hard to find.

It looks like there's an fpga implementation as part of the mister project. It could scratch the itch if the real hardware is out of reach.

You could get any Raspberry Pi (even a Zero) and run RISC-OS on it.

Even emulation is worthwhile (I use RPCEmu)

Set up a saved search on eBay so you get emails if one is listed.

They come up fairly regularly.

Be cautious of any that aren't shown to be working, especially if they don't include photographs of the area around the CMOS battery. These could leak after 15+ years and damage the board.
