In the 80s Sharp made some interesting devices powered by the Nintendo Famicom/NES technology. The less 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 and Famicom Disk System Disk Cards (and, with a 72-to-60-pin adaptor, NES cartridges too). This is the black Turbo version AN-505-BK:
Every device that gets into my hands has to be taken apart, to understand how it works and what kind of modding could be done.
Still assembled, top and bottom view:
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:
Inside view, bottom; on the lower left is the 3” floppy disk drive, on the top left the PCB responsible for power input and A/V output. The whole right hand side is occupied by the Famicom/FDS PCB and 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 is there, too.
The upper part is virtually 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. And two jumpers, the white one connects to the power/output board and the black one to the floppy.
Rather boring, the lower case now and after the last PCB and floppy has been removed:
The important parts laid out on the table:
