Mal: Thank you for your very interesting comments. Actually I didn't comment on what certification any companies had, so any conclusions you may draw about the legality of any RiscStation related operation are entirely your own.
I'm still fascinated to know, what is a Quokka? I guess we'll have to wait for the next issue of Qercus to find out.
pipalya: I've had enquiries from the southern hemisphere about sourcing 65C02 processors to run safety systems related to various sorts of railways, so the idea of RISC OS computers still controlling conveyor belts in major ports is far from surprising. (Many ports in the UK have far more critical systems controlled by RISC OS, and work is underway to move these systems to the Iyonix). David Ruck has experience of RISC OS computers surviving "difficult" conditions in the auto manufacturing industry, I believe.
Four major ports would cover most or all of Australia's major ports, right?
