il 1541 non c'entra...
ho solo recuperato una logic board del --1581-- e' ho utilizzato un case del 1541 per metterci dentro tutto quello che serve per trasformarlo in un 1581 che ho chiamato 1582 :lol:
comunque...
ho solo seguito queste info recuperate per l' occasione dal mio HD.
The 1581 was designed around the floppy drive used in the Amiga
computers, but the 1581 can be outfitted with a standard high-density
3.5" floppy drive with a minimum of effort. If you can't find an old
Amiga to plunder, here's how to do it with an off-the-shelf PC floppy:
1. As you connect the drive, match the red stripe on the ribbon cable
to pin 1 of the drive's connector. Pin 1 may be marked by printed
numbers on the circuit board, or a pin missing near one end of the
connector, or a square solder pad on one of the end pins. If you
can't see any markings, don't worry, plugging it in upside-down
won't damage it. If it is marked but the connector won't go on,
look at the key on the side of the connector. Some drives have the
shell mounted upside-down, so you may have to remove the key with
nippers or a file.
2. Turn the 1581 on. The drive's light should be off. If the floppy
drive's light is on, the connector is upside-down. Turn the 1581
off.
3. You will need to change a jumper on your drive. Write down the
configuration before changing jumpers. All PC drives are
factory-set for DS1. Change the jumper to select DS0. (If your
drive's jumpers aren't identified, try them one at a time.) Turn
the 1581 on. The floppy drive light should be on. Turn the 1581
off.
4. Now for the complicated part. PCs use pin 34 as the "disk-change"
signal, but the 1581 uses pin 34 as a "ready" signal and uses pin
2 for the "disk-change" signal. Check your drive for a jumper
marked RY or RDY. If your drive has no such jumper, you will have
to modify the cable (go to step 6).
5. If your drive has a RY or RDY jumper and you don't want to modify
the cable, you can remove the DC jumper and put it on RY/RDY. This
will get the 1581 functional, but it will not detect a disk
change, so you'll have to turn the drive off and on again when you
change disks. If you are satisfied with this mode of operation, go
to step 7. If not, put the jumper back on DC.
6. Modify the ribbon cable as follows:
1. with the floppy drive connected, write an F on the ribbon
cable near the floppy drive connector. Disconnect and remove
the cable. Note that wire 1 has the red stripe and wire 34
does not.
2. carefully cut wires 1 and 2 at the floppy drive connector,
and pull the two wires back to the middle of the cable, one
at a time, OR split the cable with a knife and cut wire 2
only
3. carefully cut wires 34 and 33 at the middle of the cable, and
pull the two wires back toward the floppy drive connector,
one at a time, so that they can easily join with wires 1 and
2, OR if only wire 2 was cut, pull only wire 34 back
4. connect wire 2 to wire 34 and insulate the connection
5. connect wire 1 to wire 33 and insulate the connection (if
applicable)
6. pull wires 34 and 33 back toward the PC board connector
7. connect wire 34 to wire 33 and insulate the connection
7. If you don't care about looks, throw away the front cover and
attach the LED board to the side of the case. Otherwise, you can
drill and mill to suit before assembling the unit. If you want to
use high-density disks in your 1581, you'll likely have to cover
the high-density hole with an opaque label to fool the drive.
quasi tutti i drive che ho DD e HD (una ventina)sono andati bene a parte uno per amiga e i dei sony per pc.
il filo rosso del flat va messo al pin 1 e bisogna inserire correttamente gli spinotti dell' alimentazione in entrambe i terminali)
(ho cmq constatato che dei drive per amiga non sono come molti dicono-plug and play. per farli funzionare come 1581 necessitano di modifiche)
( c'e' anche un altro modo ma bisogna tagliare delle piste oltre che saldare dei cavetti sulla scheda e la cosa non mi piaceva.)

se invece volete adattare dei floppy per usarli sull' amiga qualcosa ho trovato qui
