I would like to attatch a second external floppy to my Amiga 1000. When I try this by simply daisy chaining two A1010s, df1: works, but I get df2: bad, or no reaction at all. It looks like the power is not passed through or something. Can anyone tell me what I have to do to get this to work? Thanks.

The early external floppies didn't have the power hooked up for some reason, but all it takes now is a few minutes of a techie's time and probably about 25 bucks in service charges :-). // /// Usenet: uunet!van-bc!rsoft!mindlink!a23 \X/oel ///urray CIS: 73200,3117

I understand there's plenty of power available if you aren't trying to power too many things external to your amiga. I don't know what the daisychain socket on an A1010 looks like, but you might be able to add a jumper in the first A1010 to pass power. Pin 12 is for +5 volts, and pin 23 is for +12 volts. > > Bill Nichols > arpa wn0e@andrew.cmu.edu > bitnet Nichols@fnal, or Nichols@cmphys > ---------- Tom Bruhns tomb%hplsla@hplabs.hp.com

As I recall the manual that comes with the A500 or maybe the A1010 specifically states that you SHOULDN'T daisy-chain the A1010 drive. I'm sure there is a good reason for them to say that. I suggest getting a drive with it's own power supply, or a separate power supply with multiple outputs. -- //Another Julius Andrew Cisek jac423@leah.albany.edu \X/ Amiga Box 199, 325 Western Ave. jac423@rachel.albany.edu Maniac Albany, NY 12203 spcfan@ai.ai.mit.edu

When I bought my second external drive for the A1000, I had the same problem. ie, the system could not see the second external drive. This appears to be because the A1010 ? does not pass the power along. My solution was simple. Switch the order of the drives. My newest drive is now df1: because it passes the power along and the older drive is now df2:. See if this works. It's a cheap solution.

It's a cheap solution. ---------- As I remember, the A1000 does not have a hefty enough power supply to reliably (read: eventually not smoke) power more than one external floppy disk drive. That is why the original external disk drive sold with A1000 did not pass thru the power. With the Amiga 2000 I suspect this restriction does not apply and therefore new external drives from Commodore may pass thru the power. If your new drive draws less current on the voltages that matter (+12, +5 ??) then an A1000 MIGHT be able to hack it. My Amy 1000 is now 3 years, 4 months old and still purring.

I'm The A500 has a good reason -- the power supply is tightly budgeted. The A1000 was built with a much more generous power supply which can easily support two or even three daisy-chained external floppies. Charles Poirier
