Hello, dear Nemo!
Please do it if possible
repairing my board, I called you about this
about February 2.
I have: KAY-1024, GS, HDP
GS, or rather, there was, but that's another story.
One day black and white horizons appeared

Turning on and turning on the power everything seems to be

Then it was my fault (apparently uneven GS
inserted) was cor. short circuit but the computer works
Tal and then.
The following features have appeared: with HDP board
the screensaver came out, but TR-DOS did not work and
HDP too.
Then somehow the computer just started showing
When turned on, there are only colored squares. On
the board got very hot (very hot) elements D8 and
D55.
After replacing them, KAY started working, but became

vat. When choosing to boot from HDP, color
squares.
That seems to be all.
I hope that it will still be possible
revive KAY. Thank you.
Dear N!
Base: parcel dated 02/15/01 with three
boards.
1. First, general remarks.
1.1. You put me in an ambiguous position
position First of all, because the gain
KAY's board is in good condition already
impossible. Restoring the destroyed
(broken board) MGTF always removes
improves reliability and operational performance
resource Moreover, the XS 6 connector is BROKEN, due to
it is not recommended to use it,it is impossible to replace it - THIS IS UNREMON -
TIRED.
1.2. It was not worth undertaking to repair the board if
You are unable to do this or commit
this is to anyone who is FINANCIALLY NOT RESPONDING-
ET for the consequences of their actions.
1.3. Given the existing character, level and
the amount of damage I can’t say
WORKABILITY GUARANTEE. Essentially, you
you need to buy a new board. Meanwhile, re-
the montage costs money, and I owe it to you
beam. Therefore, the decision was made:
1.3.1. Repair the board for HALF PRICE,
In total, the counter showed 600 rubles. those.
SIX hours of work, of which 120 rubles. -
salary, the rest - overhead (40% -
for the repair industry). Those. amount to be paid -
300 rub.
1.3.2. Guarantees for the performance of ma-
tires are NOT PROVIDED, i.e. if it comes out
building, or it will fail, - YOU WILL HAVE TO
BUY A NEW board.
1.3.3. IDE Drive Controller Sent
back to you in the form that is - this
NOT REPAIRABLE. If you use
van Winchester, then GS is resting (you have os-
there were two slots), if GS is installed, then
The Winchester is resting. Therefore, you need to
share what to do with the IDE controller -
IT NEEDS TO BE CHANGED. Non-repairability in
In this case, it should be understood in the sense
le that a new controller board (instead of
old) will cost you less, namely:
200 rub. (including shipping). According to you
IT IS IMPOSSIBLE TO GIVE A GUARANTEE to the controller
botability.
2. Finallyrecommendations:
2.1. It is advisable to INSTALL the board INTO THE CASE
- and DO NOT TOUCH HER THERE. Constant transfer
poking the boards is an ABNORMAL MODE
OPERATION. THE CONNECTORS HAVE END RE-
SURS, namely: several hundred joints
ny, after this the board can be thrown away.
Well, it doesn’t occur to you, for example,
re-stick blocks in the TV in front
watching the program "Time". I see,
that the TV with such "exploitation"
won't last long. Sooner or later
jump something. Technically impossible
technically implement a design that
could function normally with
such INADEQUATE OPERATION. This is not
not to mention the price of such a design.
2.2. Who soldered the diode? Whoever it is
it is STRONGLY NOT RECOMMENDED that he
bother with repairs, because the result is
known in advance - getting into money.
Understand that an hour of work for a repairman costs a service station
RUBLES. Perhaps someone contracted to de-
better, the result was even more
face. The board had to be not REPAIRED, but
RESTORING, AND THIS IS VERY EXPENSIVE. Between
However, this is not a Stradivarius violin.
2.3. If you have a desire to climb
into a computer with a soldering iron, then see paragraph in the instructions
words: "soldering to the connectors, like any
re-soldering RELEASES THE MANUFACTURER FROM CA-
ANY OBLIGATIONS." It is necessary to
understand that those times when it was possible

"improved", "expanded" (to
measure of a big garbage dump) and “modified”. Te-
now he will have to pay money for everything, including
including by the hands stuck in that place, ku-
I can't get my head around it.
2.4. In case you want something special

board, then its repair (at a manufacturing company)
le) will cost 100-200 rubles. (taking into account the re-
links), and not 600 rubles, as in your case.
Moreover, the board PRACTICALLY WILL NOT LOSE any
reliability, nor in operational resource
se, nor in functions.
Application:
I. The Kai-1024 board itself
1). The VDS zener diode is soldered - soldered.
2). Diode VDЗ is reversed - re-soldered
3). The power supply path under the CPU burned out -
restored by MGTF.
(PSU from IBM PC - after all!: - and the ME case -
TALLIC?!)
4). Restoration on the reserve field of IC D55
(LL1) - torn from the board "with meat"
5). Restoration D8 (LP9) - torn from
boards "with meat"
6). Very broken(large play) once
capacity XSb - NOT REPAIRABLE
II. B-Turbo controller
1). IC1533 IE10 installed instead
531IE17 - pins switched
2) the lamella on the printed connector is cut -
restored
III. IDE board - drives: all worn out
soldering iron - NOT REPAIRABLE.
Total: 600 rub.
