remains a desire to mend his own
Scorpio, or you are unable to us
come and offer another short article on
repair.
How to protect yourself from harm
during repair.
1. Axiom. At the sting of any included in the
Network soldering iron, you may receive 220 volts.
Consequences: The average repair, rolling
in the capital.
Remedy:
a. Use low voltage soldering iron
b. Ground the soldering tip
c. If any work off the computer does not
only on the network (unplug it),
but also from all peripheral devices (TV,
printer, tape, etc.).
2. Axiom. Not picking included blocks
supply.
Implications: sad. You can lose not only pay, but also part
of the periphery together with the chunk of health.
Remedy:
a. Use high-quality power supplies
b. Not picking PSU
3. Axiom. Not everything that is heated - is defective.
Consequences: The extra work.
The board can be quite hot the following elements:
a. RAM, especially in motherboards turbo + imported analogues
RU7 b. IC 531 Series DD2 and in some older
Boards DD63
c. 556RT11 (older motherboards RT4)
Some devices can bask in
because of failure of elements to which they are loaded (the
breakdown of the entrance). But it can be determined only by
CAREFULLY cutting tracks.
4. Axiom. Duration of the signal INT AS
tionally 9 ms.
Implications: Glitches when working with prof. ROM
and with some programs.
Remedy:
a. On the old board - selection of RC - chain.
b. On-board turbo + - check circuit formation.
A snack a little news specifically
for his beloved newspaper:
1. Came out the next version of prof.
ROM 3.9e. Working with the controller and the HDD
NETURBIROVANNYMI boards. Is catching bugs ... ;)
2. Changed the firmware ALTERy for turbo
boards. Increased speed of memory operations by an average of
20%! Works with ROM V2.95 and prof. ROM V3.9e. Is catching
bugs;)
3. Came to us guys, and showed
2Mb RAM Scorpion (2 SIMM 1Mb)!! Somehow
works!? And it is not buggy with different peripherals.
That is all. On all questions write
letter ZxNews or call:
(812) 251-1262, Sergei lasers.
