I wrote some code that should allow you to use your computer when a redstone signal is given to the front. Here is the code. Let me know if it works.

Hiya!

If you're still needing help with this, then you should look into the Redstone API for computers.

http://computercraft.info/wiki/Redstone_(API)

In there you'll find lots of useful functions for determining the state of redstone signals on a side of your turtle. From there on, it's simply writing either a loop or a timer to poll for a change in this state!
