Re: RISCiX
The memory on the A310 could be upgraded to 4Mb by replacing the DRAM chips on the motherboard - a bit fiddly since they were soldered in rather than in sockets.
Mine had the memory upgrade, a SCSI podule and hard drive, and the I/O podule which replicated the BBC micro ports. I am fairly certain that it would have run RISCiX. If memory serves the hard drive equipped A400s had ST506 controllers, these *may* not have been compatible.
