no clue - PDC calls don't document that?

yes. PDC can tell you the FPU model. I'll have to look up the call.
I had the impression it was better to use FP info to identify the CPU model
than the other PDC info - but what we have seems to work.

Maybe the same call returns both CPU and FPU identifiers.
Don't recall offhand. If someone doesn't know offhand,
I'll look it up.
