Does anyone know how much the OM-2s sold for when new (late 70's)?

My first 35 mm SLR was an OM-2 that I bought in San Diego in 1977. I seem to remember it was pretty expensive at the time- $500.00 or more with a normal lens. It was a great camera, and along with a Beseler 23c-XL, made some nice pix.
