I would like to refurbish/ change my old Autohelm ST7000 autopilot control display unit, which seems to have some moisture problems to a newer (hopefully also smaller size) control unit. Of course I would like to continue to utilize the old fluxgate, drive unit and even course computer, if just possible. Is there any new control unit alternatives, which could be used to replace the old ST7000 unit?

I think this would be nice when you are attacking. If you have an autopilot on, you could continue building your base with the autopilot making reasonable decisions while you are focusing on an army.Or if you are protecting your base and have an army out, you could have the Autopilot auto-micro the army. Could be a bit extreme, but in basic cases and purposes it would be nice to have.
