A4000: Two internal floppy drives?
« on: March 24, 2005, 07:01:53 AM »
I installed another Chinon drive in my A4000 030 computer today.  It is a PC 1.44 drive that I modded to work with Amigas in 880k mode.  It works fine but when I have it set as DF1: Any drive access to either drive, both LEDs come on!  (Drive works fine alone in any Amiga) This normal for a A4000?  Or is it because its a PC drive.  I set the jumper for DF1: 880k on the motherboard.  I had to finagle the DS0/DS1 on the drives due to the twist on the floppy ribbon cable.

It seems I found my answer!  Now to figure out how to fix!

Many (perhaps most) A4000s were shipped with improperly-wired floppy
  cables. These cables had wires 3-5 twisted, instead of wires 4-6. These
  cables will work fine for a single drive, but will not properly connect a
  second drive. To use two drives that are both jumpered the same, the floppy
  cable should have both wires 4-6 and 10-12 twisted. A cable with wires 4-6
  twisted will require the drives to be jumpered as DS0 and DS1.

OK I don't think its healthy to keep replying to myself. LOL  But seriously does any one know how to get two floppy drives working with the defunct floppy ribbon cable?  Any hack I can do or do I need to get a new cable?  Where can I get one?  I assume a PC one will not work.  Thanks.
