 Hello, dear readers!

 To be honest, I did not intend to write this article at all, nor
focus on this topic. Sit down at the keyboard for me

your personal bitter experience. In short, we will talk about 5.25" drives.

 I undertook to discuss this topic because I myself have

 Now let's finish with the slightly lengthy introduction and move on
directly to the topic. So, what exactly are we talking about?

 - unprofitable, because 3.5" wheels are (much) more expensive than 5.25";- the better drive 3.5", if only it makes less noise;

 - why is it needed if the vast majority get “A” grades?

 Here are the main points that, as I understand it, prevent

 When asked what is better than drive 3.5", you can be sure
say after reading the article to the end, but it makes “noise” not less, but
incomparably less! So, rest assured, your neighbors will not
wake up.
 Now about how to “add” this very drive. Okazy-
It takes half an hour. Personally, I have Samsung, so I will have
in view of him. Absolutely the same as the “five”, even simpler. Connectors
they are identical (notsizes, of coz).

 I think that everyone knows where +5v is on their computer and where is the common one
and +12v. Don't get confused! As it turned out, my drive was enough
for 5v and general work. All connections are made by soldering
two wires. Possibly on earlier disc converter models
You will also need +12v. In general, much has been written on this topic in
various electronic publications, so there should be no problems.
 Now let’s talk about how to set the switch from “A” to “B” and
back. The button switch option is undoubtedly the most convenient!
Press the button - 3.5"d will become "A", and 5.25" - "B", press it and change -
in some places. After installing “three”, it turned out to be “B”, which told me
didn't suit me at all, because many prog's only work with
"A", by the way, which is very bad! Climb inside and blur something there -
I also didn’t really want to jump and jump, especially since
drive was under warranty. Due to the fact that none of our
there was no “three ruble”, I had to turn to SF Group for help,
after which this modification was immediately made and which I
I advise everyone to do it.
 Disk drives have a DS signal, which, depending on the installation
new jumpers, tells the disk drive to access which disk
water(A, B, C, D) to respond and that this appeal goes to this
disk drive. Inside the drive there is one signal simply by jumpers
connect to different sampling signals on the loop:


                    signal output drive
                       DSO 10 A
                       DS1 12 B
                       DS2 14 C
                       DSЗ 16 D


 These signals come from the controller, and in order for the disk drive
3.5"d. became "A", make 5.25"d. "A" drive and then wires
10 and 12 on the cable are swapped (you can, as I said, through
switch, just don’t click it while handling!) and so
Thus, drive "A" becomes 3.5"d., and "B" becomes
5.25"d. In general, you can make any drive anything you want if
it is hard-coded, for this purpose the signal to which it responds is
switch to the desired one.
 Well, why is it needed, then you can answer this way. As is known,
progress does not stand still. It sounds corny, but it's true. Early
or later the “fives” will be discontinued as obsolete,
There is already an acute shortage of 5.25" double-density drives.

degree of reliability;

Comment, do not forget to seal the hole on the floppy disk,
which is opposite the hole from the recording. And you don't need to supply 12V.
