Andrew, my understanding was that Graeme etc wanted a lookup table that they could use from within a job to find out the HS06 value from the cputype returned by the OS, not a lookup per site. The wiki lists all the cputypes used but I suspect that it is not in the form that is visible to a job.
Regards,
John
