Mystery allegedly solved. New testimony from Corey says this was a Bell Labs demonstration vehicle. Not necessarily intended to ever be a real IC. On 8/21/2022 6:43 PM, Dave McGuire via vcf-midatlantic wrote:

Perfect. 2 or 3 is a close enough for now. That's 12 to 18 transistors, estimated range.
Calling for someone that can image a die!
Thanks Dave.

Ah, so the red lines are not b/c/e? That's what I was first thinking. Here me trying to make some sense of it https://i.imgur.com/gOZujMR.jpg
Red lines inputs? Could the blue things be capacitors?
I do not think they're capacitors. Remember, this is an IC; think three-dimensionally. All we can see from that picture is the upper metallization layer, where connections to silicon are made. There are several layers below that.
Maybe purple outputs? From this view... OR gates?
Possible.
At least I have some agreement now that several learned eyes see transistors. It might be enough for our purposes to just have a good guess of how many transistors there are, and be able to identify them. What they are doing is a less important detail for our purposes at this point in the exhibit.
Yes, there are definitely transistors there.
So how many do to think you see in each group? We may never know for sure, but I'll probably run with your number as an estimate.
Well, as I said, we'd need a higher-resolution image with better lighting. We need to be able to see a layer or two below that. I'm guessing there are two or three.
