1991 acura integra 5 spd manual transmission

Hi Guys! I have a '91 acura integra with 5 spd transmission and cannot engage ANY gear, with engine running you can putnthe clutch in and out and here noo change in engine noise, rpms, or any indication of the clutch grabbing OR slipping. While trying to maneuver the shifter and engage a gear ANY gear there is no indication of it trying to engage or any grinding noises evident as if it was even trying. if you look under the car while someone is trying to shift the linkage appears intact and the shift rod pops in and out, any clues?

yep, the clutch went out...

I thought it might be that but never had an acura before, thanks much, I was given this car so don't really know its' history. well i guess I'll check into how to replace the disc and have some fun.
pleasure, Gypsy :)
