More help needed with MOTAS

Ok, Maybe I’m an idiot. I’ve been fooling around with thisgamefor too long. I’m not too proud to ask for help again.
I’m in the two story place with the big green puzzle (got that.)I have a screwdriver, a security card thingy, and a key that opens nothing. I’ve cut the green wire to open the second laser gate. I’ve found the series of numbers on the black locker. I found 2 secret passages, one to the hall on the lower level and the other into the room beyond the second laser gate. But, now I’ve been wandering in circles for days. I’m getting hungry and thirsty.

HELP! get me outta here!

Good game, I’ve played it many times. Here’s a walkthrough for the game. You’re on the last level.

Oh, and Og smash.

You ARE my hero. Little did I know the answer was right there in front of me all along.
I’ve escaped. I’ve had a bite to eat and something to drink. I believe I’ll live until I get trapped in the next game.
