This nice system was built in Japan by EPOCH and sold in europe (mostly and maybe only in France, where it was distributed by the well known pong seller ITMC) under the YENO brand.
Successor of the Cassette Vision (1981) and Cassette Vision Jr (1983), units that never hit the european market, the Super Cassette Vision system was an unsuccessful competitor of the Nintendo Famicom in Japan. In France, on the other hand, Yeno had the opportunity to sell a few thousand units before the beginning of the marketing of the NES.
Built around a Z80 clone, the Super Cassette Vision was a good system, but with only about thirty (although of good quality) games, its sales remained anecdotic. EPOCH developed many of the available games and later sold a limited Lady edition, bundled with a pink carrying case and the Milky Princess game.

I had the french version of the Super Cassette Vision under the Yeno brand. I far as I can remember, the cost of this memorable console was about 700 french francs at the time, which was about 120 - 140 US dollars back in 1988 (I guessed it was about that year - I was only 11 at the time). Anyway, I remember it was a very ice console althought it was a hell to put the two joystick back under the front semi-transparent black cover. The cables would never turn in completely. Also, I remember games were pretty hard to find. The console was a present from my parents and I belive it was ordered through a mail delivery catalogue like the french "La Redoute" or "Les 3 Suisses" which are still very popular and are still selling consoles (newer one off course). Hope this will add a few more info and thanks for your great website!
