Ouch.  When I was your age, and at that level of technology, I war doing
one-sided layout, routing only the power and very few short traces. Then
I copied that layout to a bare copper layer by transfering prefabricated
lines from a transparent sheet to the copper.  Most connections were
later added with wires, the kind of wire used in transformers, I do not
know how it is called in English.  The insulation melts while soldering
it.  That was 25 years ago.
