I need some advice from peoples who are using a Chinon FZ 354 drive as an amiga drive. I want to add one as an external drive to my A500. I tried to replace my internal drive by the Chinon, and it worked,but without disk change. I think I have to configure the driver's jumpers properly. What is the correct configuration? The jumpers I found on the back of the drive are: DS2... ....DS3 . . ....MD . . . ....RDY . . . . o-o-o o-o o o ! ! !...TTL/CMOS o-o-o o o-o o . . . . . . . ...DC . . ....MM DS1... ....DS0 The default configuration who came in the drive are DS1,MM,DC,TTL. If someone could give me an explanation about each one, I would be very happy. * Gelson Dias Santos * Bitnet/Internet: GELSON@SBU.UFRGS.ANRS.BR * * Porto Alegre - RS * Sorry, english is not my native language! * * BRAZIL * (Alguem fala portugues?) *

Try changing the jumper from DC to RDY. On the IBM-compatible Toshiba drives I have, the DISKCHANGE signal is jumper-selectable to appear on the RDY signal line instead of its usual place (on pin 11, I think.) It appears that changing the jumper might move the RDY and DISKCHANGE signals back to where the Amiga expects them. ------------------------------------------------------------------------------- The DiskDoctor threatens the crew!

First of all: I would like to thanks John H. Lee <johnhlee@cs.cornell.edu> and Hal <hgm@ccvr1.cc.ncsu.edu> who sent me instruction on how to do this drive work properly, including disk change. Second: If you are not one of the guys above, but sent me a mail, well, I think my host lost it. We had a disk crash this weekend and all mails received from last friday to this monday morning was lost... I still have some problems: I want to use that drive as an external one, but until now, it work only when I replace it by the internal. Looking on the drives pinouts on the docs, I found a little difference between the internal and external connectors: the external has a line called IORESET. Where have I to link this line in the drive (pin number)? In addition to this, is there any other thing to do? A friend of mine (who is trying to use a identical drive) said me maybe we need a little interface (?) to connect this drive as an external. A flip-flop or something. Is it true? My system is an A500 1M rev.5. The drive is an Chinon FZ 354. * Gelson Dias Santos * Bitnet/Internet: GELSON@SBU.UFRGS.ANRS.BR * * Porto Alegre - RS * Sorry, english is not my native language! * * BRAZIL * (Alguem fala portugues?) *
