A DC10 crew, on climb out over rbv, experienced an INS malfunction, which caused an over correction to capture outbound course. This, in turn, required a corrective vector from ATC.

Narrative:
We were proceeding direct to rbv then on to saame intersection. At rbv, the #1 INS went temporarily in-operational and attempted a 180 degree turn back to rbv. We caught it at approximately 30 degrees left turn. ZNY gave us a 90 degree intercept (right turn) back to the airway at approximately 5-8 mi, past rbv, then a 45 degree intercept. It was too much for the 'old girl.' we went through the course and were given a vector back. (We were correcting on our own anyway.) nothing more was said.
