I have an older legacy PCI board (designed for receiving data from an instrument). I am now upgrading my computer. New computer does not have the older longer sized PCI slots. All of these have PCI-X slots. Is there an adapter that will enable me to use the old card in these newer slots?

You don't need an adapter but you do need the PCI card to conform to the 32bit 3.3v "Universal" PCI v2.2 specification.  PCI-X slots run at 133MHz but will drop back to 66MHz if a legacy PCI card is detected.  The whole PCI-X BUS will then run at the slower speed.

If your card is designed for the more common 5v PCI slot it won't work.

My PCI card will not fit it the new slot. So, I guess I am out of luck.
