[comp.sys.amiga] chaining disk drives

No, you can't plug more than one external 3-1/2" floppy into the Amiga
without having another source of power than the Amiga itself.

You can build yourself a power supply fairly cheaply (< $50 for something
robust -- maybe less than $5 if you look in the right place).

A while back Radio Shack was selling power supplies which I believe were
surplus supplies for Coleco "Adam" computers (?) which I think had 
enough capacity to power one drive.  These were three or four dollars apiece.

You just need to hack a connector to go from the output of the first
drive (the one connected to the Amiga) to the input of the second drive --
this connector just needs to pass all the regular signals and insert
power on a line (or a couple, I don't remember offhand).  The A1010 doesn't
feed power back out on the connector on the back; it's trivial to add
these lines.  Check your documentation....

Alternatively, you can pay someone else to build it for you ---
if you can't find someone and want to purchase a supply, send me mail --
a friend of mine is making supplies for just this purpose (I often run
with two or three external drives).  I won't say anything more about 
this here though since I don't want to get too commercial on the net.
