Yes, I was curious and a bit skeptical when I heard that they fit these scientific operations into 320 instructions. That's what motivated me to look at the chip in detail, to see how they did it.

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/...
