Regarding the 2nd board:

Is there a likelihood this board could trace back to the Vancouver, B.C., Canada region? - there was an "Intek Electronics" near the south end of Main St in Vancouver in that era (70s-80s). I don't know if they had other outlets across the country.
It was a component supplier/retailer but like other such retailers it might have been a kit or in-house effort made and sold by them.
