I used a ceramic oscillator (2 pin) on a 16C65a design.  You connect each
pin on the Xtal Pins, and The Caps on the outsides

Fellow Piclisters

How do I go about connecting a *two* pin resonator to an '84? The schematics
I've seen so far show a *three* pin device, with a pin to ground. And are
external
caps required?

And while you're here, everyone who's an electronics bod will know
instinctively
how to make a Wein Bridge oscillator, but I'm a computer bod, so I don't. If
anyone could oblige with a schematic (ascii or otherwise) with values on
components, I'd be very grateful. Horowitz and Hill have an example, but
with
a miniature incandescent lamp that I can't identify. Adjustable frequency
would
be a special bonus.
