Sanyo/Fisher Boombox/Portable Ads and maybe some Craig?

Wow, a neat little cassette player from Sanyo 1975, pretty cool that it's paired with a cool calculator. Anybody own one of these?

1988, the Remocon (remote?) is less expensive but overall they look the same.

 

If I had to guess I'd say around 1972? I don't think I have many old Sanyo's kicking around, I had to look cuz the design is very similar to Sony's Offerings at the time. I love the swag box, two tapes and a Mic, there's probably a earpiece in there somewhere.
