My problem is I've not done it before. I also have the
logic-analyzer-on-a-chip out of the 165xx series shot but
not analyzed.

Don't you also need to "delayer" the chip to get all the hidden
features? I thought the process of reconstructing the polygons
required that each successive layer be exposed. From the "top" I'd
think you'd only see a single metal layer. But then again, on a old
chip like that there may only *be* one metal layer :-)
My primitive understanding is that there will be a "base layer" with
junctions and one or more metal layers on top doing the interconnect.
(I try and steer clear of physical design, or "PD" as we call it, since
it's seriously complex. but also interesting!)
