   WHwhat is it, and what is it eaten with? Idea
this device is borrowed from 
Amizhnikov, where, in fact, this comes from
strange name. Most Amigas, ra-
Those who work with disks are usually equipped with -
is a similar device that serves for
in order to "swap" the 3rd and 5th
inch drives.                      
                               
  Let us immediately stipulate that the said “establishment”
swarm" is of interest only to
owners of 2 or more disk drives (or
for those who are planning to get a car
rim drive). Quite often old (and
sometimes new programs also refuse
work on the second drive. Of course
This problem can be circumvented by running without
pamotho composed "products" only with
first drive, but this is not always the case
convenient, and not always possible - for example,
measures if you have a second 3'5 inch
disk drive tightly sealed in position
"B".So, how can you quickly change
drives in places, without rearranging each one
times jumpers?  Very simple. Let's remember
how the controller shows the worker address
drive:                               
   The disk interface connector has
4 contacts - numbers 10, 12, 14, 6,
the phenomenon of the signal on which, respectively
determines the numbers of drives A, B, C, D.
Disk drives depending on their number
react to the appearance of a signal according to
corresponding line.                       
   Thus, in order to change
the drive number is enough to change the month
those wires that determine the number selected -
new device. It is convenient to do this with
by the power of the switch...                   
                               
 For work you will need: a soldering iron,
wire cutters, wire and switch for two
contact groups (such as ordinary
double toggle switch on mics). When
the power of it all you need to figure out
something like this:                      
                               
                     -+-                
                     |                  
 SEL A  >-------+--- | |                       
 SEL B  >----+--|--- |-----> SEL A    
             |  |     |                  
             +--|--- |                  
                |                       
                +---- |-----> SEL B    
                     |                  
                               
 On the left - signals from the disk controller
yes, on the right - signals after the switch,
going to disk drives. All. Now it remains
just make a hole somewhere and
screw the toggle switch in there, after which you
with a slight movement of your hand you can change the
measure disk drives without tweezers and soldering iron.
