FDD - all i know...
that's it, God himself ordered the disk drive to be taken from
pisishnikov (read - cheat!) and fuck with
Spectrum! the situation is so favorable right now
happened right now, coz cool japan-disk drive (everyone’s dream
wild spektrumist by the way!) can be bought for 20
someone will give you rubles or something like that for something - what’s the matter with him?
they should do something right now!
=what they are:=
5.25 drives are available on xt and 286/386 (less often). if you found
xt, then most likely the drive there is ds/sd (ХОtraxx) or
- 3bOkb! and it won’t be of any use to you. how to determine:
who knows, just try formatting the floppy disk in
modes. if so, the recipient will receive it as usual
(8Otrks) no - that means it’s him. meet me. or simpler -
look at how fast the wiring goes to the disco-torque board
engine, if four means exactly 3bOkb. no luck.
but notget upset - you can throw it away. or put
on the shelf. (4 fdd - kollekshn) I have one by the way.
the next step in the development of writeable drives... who
said - ds/dd? no fucking way! as I found out, they immediately began
do 5.2Sds/hd, but not the same as on 3.Shd, and the other -
only 1.2mb! (everything is different from db)
well, you connected it to zx, you even connected it and that’s it
It's cool, but it's loading - I don't want it. and they can’t. in my head
thought - what the fuck? (or something like that - thread
like this one). and the thing is this - (probably) - disk drive
high density! How can I wash this off? first of all, he has
The engine is not turning as well as it should. it is necessary - 300 revolutions, a
he is in a hurry and spins the round iron thing 360 times
(per minute)! Fucking possible! Of course you can smoothly
adjust the rotation speed. everyone was probably surprised -
how? how-how, you grab it with your finger and slow it down
neat! I even managed to load boot - here
what a great guy I am. but somehow inconvenient (in front of the drive).
so there is another output - there are a lot of jumpers on the drive
all sorts of things, all sorts of inscriptions next to them, for example -
hs,dc,is,u0,u1 and something like that. maybe one of them
and switches the drive to ds/dd mode - I have 3 of these
came across. But! before the start of an exciting game
"try different things" don't forget on a piece of paper
draw how everything was before in order to put everything as it was
it was, if nothing was received. if this happens, then bet
them in their places and move on to plan "b" (be).
plan "be". after that the engine will spin exactly like
necessary! turn it over and look for the toggle switch at the bottom next to
which says "300/360 switcher". Well, did you find it? no
what? ok, then look for 5 wires that
connects to the engine board. connect to it: gnd,
+5v, +12v, something like motor op/off, and 300/3bOselect
(you have to find him).
take a tester andlook where what is. you can find the first 3 easily
(because they are connected to the power socket), motor
op/off is also not particularly difficult - connect a tester to it and
try to load something at the moment you access it
this signal will change from 0 to 1.
In short, there will be tension there. and now there's only one left
wiring - that's it. He's the one who ruins everything. if there is one on it
5 volts, which means you need to unsolder it and connect it where
it connected to gnd. and if not, then it’s the other way around
connect to +5v. Well, the engine should switch
by 300!
if the engine has switched but the drive is not working yet,
that means rearrange all the jumpers again and you can still
Connect the second contact of the data/control connector to gnd.
should work.
and also - someone somewhere shouted that something appeared
the ability to write to 5.2Shd disks (in the sense of just like
to regular ones), a regular, Russian drive is not
got it! no fucking way appeared! that is, write something down
write it down, but read it allit will stop in 10 minutes,
If the disk drive switches to ds/dd, then the write current
also a switch, I read in some book - for HD -
600 a for dd - 300 (there it’s all in some left
units were measured, this was the first time I saw such things). i.e. in HD
floppy disks magnetic sensitivity is 2 times lower.
although you can’t write anything with a Russian floppy drive, apparently
he has exactly 300, and the bourgeois one has a little more, so
He can write it down, but it won’t last long! but on
It writes regular floppy disks better and lasts longer.
tested on three such drives. I have these floppy disks
- a whole mountain lies, and nothing can be written down on them!
[paint it yourself]
one more piece of advice - as a rule, if zx is not in writing
box, then its color is most likely black, and these
the drives on the front are all white, so: unscrew
front panel (most likely it is built on two
buhtukax from below), wipe it, for example,
646-solvent, take a can of black paint
(preferably matte) and paint it black. in a couple
hourswill dry out. done - you have a black panel! himself
I tried it - look - awesome!!!
[briefly about 3.5 drives]
there’s probably no need to tell anything - and so everything is about them
known. if it is HD, then the switcher is inside on the right
(if you turn it towards you in front). pin pressed -
switch to dd. if the optocoupler is something like the same (itself
you understand)... you can either close it on all your floppy disks
make a hole on the right or something with a pin /
optocoupler. choose what is more convenient for you.
[and I can’t remain silent about it!]
a I have twenty eight-inch basf floppy disks between
other things. not used at all. found some practice
took place in the judicial service npuctabob (archived). fucked up
I was so happy!
well, I think I told you everything I know about disk drives,
try it, write how it goes! [!КOНETЦ]
