I found the collector's guide to Vintage Intel Microchips and used it to look up several chips, but I have some questions on several of them.
It said that there weren't any P3408 Chips. I have a P3408A. Is this a rare chip?
I also have a P2125-2. I didn't see this variation in the book. Did I miss it?
Also, I take it the C1103 is a rare and significant chip. I believe i have the Type C purple ceramic package with w/gold cap and gold pins? I don't understand the date code on the C1103. It has H9035 for the date code; wouldn't that make the manufacture date the 35 week of 1990?
Also, I have multiple chips with the triangle with the s in the center. I am curious what that symbol means. |

Its an early chip, but a support chip, and one thats function was made by a lot of other companies, so not in many collections.
Neat find though and I would say rare

P package not in the guide but not surprising at all to see, especially with alate lot number as yours has. Released in 1976 so I would have been shocked for it NOT to be in PDIP

Testing mark for whoever the OEM is that used them, fairly common in early stuff where the OEM would test EVERY chip they bought before using it
