Wow! That $84.95 was a hunk of change back in those days. I was making about $1.65 and hour (about minimum wage then)in about 1969. I don't know when those came out but that would be like $800.00 or more today probably. I have a old Humminbird super sixty in the shed that I bought in the early 70's and been buying Humminbird ever since. But like you said I think the green box came first.
