Are you 100% sure of that? I was udner the impression
that the WD p[art
needed some -ve supplu rail (-12V?) and that the Fujitsu part didn't, the
pin was a N/C. The Fujistu chip will replace the WD with no problems, but
the reverse may not be true (and IIRC, the HP board that started this
doesn't have a -ve supply rail).
On my board that chip has +5V and +12V on pin 40.
