I wish I had a copy of it, (but don't), but John posted a message quite a bit back about that very thing! You don't need any chips on that level. I hand wrote his message..may have been getting one of those 'can't print now' messages. Here's what he gave us :
D11, R2, D6, L2, D9, L2, D2
Now keep keying right into the force field. When you get kicked out, go back to the same spot & force key right again until it finally takes you to exit. (Thanks John)
By the time we're all finished mapping, I 'll bet we find a few more gems like that!
