Thanks very much for your response. Seems like the more I learn about this fascinating hobby, the more I realize how little I really know. I've been relying on C&W 4th Edition as a good reference, but I've noticed some significant holes in their info recently, this being a great example. I could have paid a lot more for this chip than it was apparently really worth. Perhaps a combination of the TCR and 4th Ed. would make more sense.

Suffice it to say...thanks for the edification!
