After years of unbridled desire and extensive research on markets and online auctions, I finally filled a big gap in my collection (and in retro-collector affections of mines), getting myself a Sega SC-3000, although it shows with a different brand. Yeno was a French company that handled the distribution of the SC-3000 on its territory, a deal with Sega to sell computers under its own brand, reserving the name of the original manufacturer to the upper right corner of the case, labeled white “Manufactured by Sega”.
The Yeno SC-3000 is in all respects identical to the Sega design, with the exception of a very good quality RGB video output , thanks to an additional card installed inside the case, mounted in piggyback mode, and connected to different pins, with obscene flying cables, to the motherboard.
The R/F module originally present in almost all manufacturer's machines, is absent in all specimens distributed by Yeno on French soil, which show a sort of rubber cap in place of the R/F output.
The Sega SC-3000 is closely related to the SG-1000 console, with which it shares the same technical specs, while adding a full membrane keyboard, with rubber keys in ZX Spectrum style.
It was this additional feature to make it a commercial success, and make it more palatable than the corresponding console version.
