Homebrew PCBs

Hi guys,

 

I've been continuing to research and amass parts for my TV Typewriter
replica build.  I have a blog of it here: http://bradhodge.ca/blog  --
mostly working on the case right now to inspire me to push forward, but I've
succeeded in getting almost all of the vintage 1973 or earlier chips I
needed.  Now I'm down to the PCBs again.

 

I guess I'm still kind of 'green' on this sort of thing.  Ideally, I'd like
to do my PCBs the way they would have in 1973.  But I still don't understand
how that worked.  Don Lancaster said the boards used were green G-10.  I
found this on ebay:

I guess what I'm having trouble with is understanding how a home PCB maker
in 1973 would have gone about getting copper onto these boards and copying
the artwork from the article.  Is there any really good, baby-steps reading
out there?  I just want to understand the original process and if it is
possible to replicate it here in 2015.  I sort of understand the idea behind
photo lithography.. I'm just not understanding how copper ends up on board,
etc.

 

Much appreciated!
