Homebrew PCBs

Hey guys,

 

I have recently heard of some methods of 'dyeing' PCBs to achieve coloration
closer to what vintage PCB stock looked like.  I'm wondering if any of you
have experience on this, what works, etc.

 

I recently acquired some original, untouched Mark-8 computer boards:

I'm hoping to use them to help create replicas.  But I just can't get the
PCB to look the way I want.  They look too modern.   I've heard dyeing can
help, and that one can even fake the fab house marks somehow.

 

I'm surprised there isn't a stock of vintage copper clad out there
somewhere.  Seems to be vintage everything else these days in electronics..
