Narrative:

During takeoff roll V1 and vr were not on the speed tape. Accomplished callouts by referring to FMC display and reference to the speed tape. All other speeds were on the tape. (V2 and flap retraction speeds.) we don't know why this happened but would like to. New FMC software version was installed.
