In the 80s, Sharp made some interesting devices powered by the Nintendo Famicom/NES technology. The less well-known devices are the Famicom Titler, a video subtitler, and the C1 NES TV/Sharp Nintendo Television, a television set. More common is the Twin Famicom, a console that plays Famicom cartridges, Famicom Disk System Disk Cards and NES cartridges (with a 72-to-60-pin adapter).
This is the black Turbo version AN-505-BK:
Top and bottom views and a close-up of the label:
This is interesting: Behind an access cover, there is a bridge that connects the FDS PCB with the floppy disk drive:
I take apart every device that gets into my hands to understand how it works and what kind of modding could be done.
Inside view, bottom: On the lower left is the 3” floppy disk drive and on the top left the PCB responsible for power input and A/V output. The Famicom/FDS PCB occupies the whole right-hand side together with the cartridge eject mechanism:

Let’s remove the Famicom/FDS PCB:
The lower part of the PCB is virtually the Famicom part. It has the power and reset switch, connectors for the two controllers, and the Famicom extension port where you can connect external controllers and peripherals, e.g. the 3D glasses or the Power Glove. The switch for Famicom/FDS-mode and the FDS access LED are there, too.
The upper part is the FDS part. There is another extension port that allows a Nintendo Famicom with a plugged in RAM Adapter to make use of the FDS drive. The two connectors on the left are for the power/output PCB (white) and the floppy disk drive (black).
Rather boring, the lower case now and after the last PCB and floppy has been removed:
The important parts laid out on the table:
