Famicom Disk System

The following article explains how to make dubbing cables that allow the connection of two FDS drives. The cable will allow the copying of a disk by using one drive to read the disk and the other drive to write the copy of the disk. There is also a brief section discussing bypassing the drive’s write protection circuitry.

This tutorial came from a book called Famicom Kaizou Manual (Famicom Remodeling Manual, or Famicom Modding Manual). This “mook” (magazine book) came in three volumes and is a sister publication of the “mook” Backup Technique, which ran for 38 issues plus two bonus “best of” issues in the ’80s and early ’90s. It was renamed Game Lab (Game Labo), and is still in publication today.
