In this paper we present measurements of the temperature dependence of the upper critical field H/sub c//sub 2/ and of the magnetoresistance for V/sub 1-//sub x/Si/sub x/ superconducting amorphous alloys. Negative deviations from the classical variation of H/sub c//sub 2/ in a dirty superconductor are observed related to a positive magnetoresistance due to weak localization in amorphous systems with finite spin-orbit coupling. These deviations can be qualitatively explained through the model recently developed by Coffey et al.
