UPGRADE - To the question about installing 3.5 'FDD.

               "To put or not put,

               That is the question! "


   To a question about installing 3.5''FDD.


  Sure bet! And here's why.

  Floppy disk. With each day to buy the normal disks 5.25''more 
and complicated, but in Armavir and costs pyaterochnye drives 
razed to troechnymi, and then and surpassed them.


  Compatibility. When iBMschikam was asked about compatibility 
and alignment in their eyes shone with such a misunderstanding, 
and hair stood on end diligently to address: "And what they

then load it ????!!!".

  But those who just want to put
currently flopovod. Buy branded "troika" is cheaper than even 
5313, but for "TEAC" I generally keep quiet, though normal, 
"TERN", and not the 40-track. 

  How do I connect? It's very simple.

  Phase one: buy a floppy drive. Most
cheap drives in Armavir in the Rosselkome "(second floor 
entrance of electrical plant). Will drive any. What you may 
encounter: from plant density, with the choice of installing 
the drive or without them. The latest models without any 
jumpers, and that you have worked floppy HD, need to seal the 
window density diskette. Without selecting the drive - but still

well they can put on A: and
In:. Pay special attention to how stress your drive is powered, 
but it already during the installation. On the drive must

be shown how U want it -
only +5 V or-12V and +5 V. Please
special attention to this.

  Phase two: find the necessary connectors. Connector on 
Nutrition you can ask for iBMschikov friends or go to the store 
"Maison" (in the courtyard of a musical school), they do 
sometimes. Now - system connector - you can buy ready-made

plume in any iBMoshnoy office and kill him in Fig.1 (sm.ris1). 
Now can only connect. Power connector at the three matches 
pyaterochnomu. A plume troechnym connector should turn 180 
degrees (see Figure 2). That's all. If there is something you 
do not understand or something does not work, then take a look

carefully ad.

  If you are not a lot to think and see
scheme, it is possible with a single
toggle organize switchable pair 5.25''- A; 3.5''- B, one click 
and obtained 5.25''- B; 3.5''- A.


  Teper's something else, I hooked a triple normal "Pentagon", 
without any turbomurbo and PLL AMDH and other gadgets. Tr-Dos 
version 5.03 and all works great. Also, I tried

work in the Is-Dos, pumped texts
Ms-Dos 720 and back perepysyval protected floppy (unless of 
course you can do it) - everything works.


   Well, the last point in this article:
HDki if you are taking is already formatted (Ms-Dos 1,44), do 
not worry. If your PC before it is normal formatted disks 
5.25'', then the triple He also will format correctly. I tried 
this statement in the six boxes 3M and box Verbatim, formatted 
in the Ms-Dos 1,44, just do not forget to seal a floppy disk, 
or switch density at the Flopper (if that

switch).

   So put, it will work.

Supplement 1.
--------------------------------------
   So far, all prepared (magazine) received new data - got my 
hands on three drives - I drove them - compatibility class! And 
on his own, so that all time not to glue pieces of paper, I 
shorted HD signal on the sensor, and now nothing

Gluing is not necessary. And now, less joyful information: 
perhaps on the old the very first schemes controllers troechny 
flopovod bad format, although writes that if someone is normal 
format and reads well, although 5.25''works fine, until the 
reasons not clear. There are opinions that do not have enough

Bias current (but it's still theory).

   And here's what to consider. In the 3.5''
FDD terminating resistors, as in
5.25'', no. If you put a troechny
drive here will have to invent something, because likely to 
operate as a drive is impossible. By pyaterochnym is treated 
exactly, but to troika? While little information.


Appendix 2.
--------------------------------------
   There is one more additional and not quite pleasant 
information. 

   If your triple sensor HD / DD
pressure action, and others I have not yet
saw and saw I had four models, there may be an unpleasant thing.

   Feeler gauge pushes capping
your floppy disk, and flopovod ceases to understand that you 
have a floppy, DD, is still not the most unpleasant, but when it

occurs when the census, particularly track-cam, even with 
simultaneous format, and the original you like it then

use, without checking a copy, go on
I'm longing to catch up not budu.Chto you can do the most 
drastic short-circuit sensor, and then solved by another 
problem - if the belt paste floppy. Or if you can not do it For 
some reason, after writing do check the disk, and if after 
drive started fooling around before Restaurant Check capping or 
switch it. 

   Conclusion: The better one time to deal with
sensor, fewer problems.
