Does anyone have any idea what this IC is? <http://www.classiccmp.org/hp/Unknown%20IC/Unk%20IC.jpg> This is the

one that I've found but I haven't been able to find any information on it. Not even who made it. It's a standard .3" wide 16-pinDIP and it's marked PX032768 (9003) and it has a small window on one end. Inside the window

what looks like a tiny tuning fork or something. Any ideas?
