I have some drives I?m trying to find the manuals for, I have 2 Chinon, a FZ-502 and a FZ-506 and a toshiba 360K drive that I?d like to find manuals for. Chinon has long since stopped making drives and I was unable to find any information on their site for disk drives and no luck on the toshiba site. These were tested good about 10 years ago, but I no longer remember what they were tested in and do not know the jumper settings I need on them for sure (and some of the jumpers are not labelled :(
