A great deal of the material used to document the FAT8 and N88 Stand-alone disk basic came from the 1993 Disk tutorial by Seijuro (Yuo Kawarasaki) NIFTY_Serve QGA02240[UJO0489,JUP2009B]
Much of the details for the individual formats came from the research by the guys at the FMV Forums as well the open-source code for the NP2Kai emulator.
