Now that is something I didnt think of. Though I would have thought that
the card wouldnot have seated properly had this been the case. I would
think the motherboard is a 5V one - AP400's are not very modern machines
after all.

That was my impression. Subsequent enquiries to Compaq have elicited
an "it will not work" statement, but no indications as to *why* it
will not work. I have an alternative machine which has a much more
recent motherboard in it (non Compaq) which should support 3.3V PCI
so I can try it in that. Else it looks like I am
shopping for one of these 'PCI-X"things on the weekend.

Thanks for the advice,
