Anyone got the oem Honda factory service manual for a 1980 Honda accord. Not the owners, but the shop one. Any electronic diagrams ?

Looking for the shop service manual and the electrical troubleshooting manual for a 1980 accord hatchback and ik there’s a shop service manual that’s way more deep than the owners service manual. I seen an 84 accord electrical troubleshooting shop book as well so if theres a 1980 version of that I need it as well.

I heard of some old electronic diagrams existing and hope someone has them. I’m willing to buy.
