I bought my FA new back in '87. It was a fun camera to use, but around 1996 or so it started to develop problems. It started with the blank frame problem (as described by lawrenceimpey) but gradually this became worse until eventually the shutter wouldn't fire at all. Sometimes I could "reset" it by switching the shutter speed to B or M250 or by removing the batteries. A CLA seemed to fix the problem, but after a short time it quit working for good. Given Nikon's reputation, I was surprised that the camera died after only 10 years of light-moderate use.
For technical specs, operation and any specific questions, this is a good site to look at:
