I tried to look for specification of AHA-2940U2B in Adaptec website and all I found are information for other models in Ultra2 Family, such as AHA-2930U2, AHA-AHA-2940U2W and AHA-3950U2.

I broaden the search and finally found a PDF file in IBM website. The Adaptec AHA-2940U2B specification is listed under [UltraSCSI Contrillers(PCI)- withdrawn]. By the way, the PDF file is dated back to year 1999 and according to the PDF file, AHA-2940U2B was withdrawn in October 2000.
