Acorn RISC PC

I got this machine from eBay in November 2018. It has RISC OS 3.71 in ROM and came with a softloaded version of RISC OS 4.02 on the hard disk. It has 160MB of RAM with 2MB VRAM. The CPU has been upgraded at some point to a DEC StrongARM running at 200MHz. I plan to sort it out with a more modern storage solution to replace the 3GB IDE hard disk and would like to see if I can get it softloading the different versions of RISC OS up to and including the latest builds.
