Maybe that is what it was called, the free trade zone, not the industrial park, IDR. I only went to Penang once. I remember an area a few miles away (~10?) from NatSemi that had a cluster of other big name US Semi companies and signage on the buildings readable from the highway. That must be where you were. IIRC, Fairchild/NatSemi had the first American assembly plant in Penang, the plant was built before the free trade zone was created. The "highlight" of the trip was going to a restaurant on the water. It was night time with moonlight out in the sticks but this place was a shack, very rustic mom and pop style restaurant where your bare arms would stick to the table tops. We picked out a live fish in a tank that we wanted to eat. They killed, cleaned and cooked it, brought it out to us on a platter, set it on our table and then chop-chop-chop-chop the waiter cut it into about 12 big chunks for us, bones and all. We dug in with the chopsticks. The Chinese Engineering manager that brought us shoveled the fish into his mouth, expertly separated the bones and spit them out on the table beside his plate. No napkins there. I had never seen anyone do that before, cringed due to my western norms. IIRC most every other bar (other than "The Ship") was into karaoke at the time. Funny to watch the Chinese and Malay girls trying to sing American songs. I much preferred Singapore over Penang.
