2165.0. "2 Internal floppies for XT card." by MQOFS::LEDOUX (Reserved for Future Use) Fri Jan 27 1989 15:05

I need  someone with  some  knoledge  about  floppies  connector.

I own  an A2000 and I need (internal) 3 1/2" floppy (720K) for my
bridgeboard XT.
I  disconnected  DF1:  from  the  Amiga and made a cable (34 pins
berg to  berg  with  card  edge in the middle) that works fine...
after  adding  a  wire  from  the  external  connector (SEL1B) to 
internal  connector   pin  12.   BUT  when  I  use  drive  A:  on
the IBM, both LED on drive A: AND B: lights up.
Like  I  said,  IT  WORKS, but the fact that BOTH leds are on  is 
a bugger.

I  am  trying  to figure out WHAT is getting the LED to light up?
Hit <CR> for more details:

If I use drive B: only the drive B: led is on.
If I use drive A: both Leds will light up...

Here is the drive config on my Bridgeboard:

PHYSICAL DRIVE 0	 |	  PHYSICAL DRIVE 1          | PHYSICAL 2
	 		 |				    | 
    Drive A: 5 1/4"      |        Drive B: 3 1/2"	    | 30 Meg Hard Card
READ:	 360K		 |		360K		    | (drive C:)
WRITE:   360K		 |		360K		    |
	 		 |				    |
 Virtual H: (drive A:)   |  Virtual Drive I: (drive B:)	    |
READ:    360K		 |	 	360K/720K	    |
WRITE:   360K		 |		720K		    |


NOTE: IF I change PHYSICAL drive #, now BOTH LEDS will light up
      for drive B: .  i.e IF I use the 5 1/4" drive, it also lights
      the 3 1/2" LED.

My question is what signal do I have to modify to get it to light
the proper led?
Or if you prefer what is causing the 3 1/2" led to go on?
