Clutch Cable Adjustment

Hey everyone, i have an 1985 Turbo SVO and im having a little trouble taking it in and out of gear. Feels like its still biting and not letting go all the way when i push in the clutch, as well as being difficult getting it into first. Im thinking that its simple and it just needs an adjustment of the cable. But i have no idea where to find where to adjust it. I heard that there is a knob or something that you can tighten and loosen?

Yes its the OEM cable and everything. Thanks alot ill try that on my lunch break and see what happens!

So i tried pulling the clutch upwards like you said.... and i think the cable ended up coming off of the clutch pedal. Fell off while i was in the midle of the street... I looked underneath the car to see if anything was broken and its not. But the pedal is almost to the floor. But when i press it it still moves a little. Any helpers out there???? I got work in a few days and thats my only transportation.
