Do you have any good suggested reading material on how to look at chips in the way that you mean? I have no knowledge when it comes to this type of hardware.

For understanding chips of that era, one good source is Introduction to VLSI Systems, which has a PDF at: https://ai.eecs.umich.edu/people/conway/VLSI/VLSIText/PP-V2/...
