MODEL OF 1966
CHIP REPLACEMENT
Ostankino requires Moskwa
microcontroller ICs to be
replaced. The new rmware
revision that takes advantage
of the expander functionality,
improves the performance and
adds some new features.
Turn your system off, then
unscrew and unplug the mod-
ules. Put them on the table,
knobs down. Now, remove
the old chip. Pry it up gently
using a toothpick or tweezers,
as shown on [Fig.1]. Then, put
the new chip in place. Observe
the orientation carefully, the
notch points down! Then, gen-
tly, push the chip until it sits
safely in the socket. Repeat the
operation for the remaining
Moskwa unit.
CONNECTING THE CABLES
Looking at the back side of
modules, attach the 16-pin
inter-connectors as shown on
[Fig.2]. The red stripe points
to the right on the Moskwa
(
expander header, remove
the jumper rst), and points
up on the Ostankino (a and b
header, should arrive attached
already).
Clear 50hp in your cabinet and
place the modules in it. Only
Moskwa A requires a power
cable now (you can simply
remove a power cable from sec-
ond unit). The expander module
and second Moskwa will draw
their power from the rst unit.
Finally, check if the orientation
of the power cable is correct,
and thats it, you’re good to go!
