Iron - circuit for disabling the eighth page of RAM.

Yuri Nazarenko/Rezident/N-Discovery

   Here is a small circuit I developed for the
turning on the eighth page of RAM! She's right
valid only for yellow scorpions. B
As a switch, any
locking button. The operating principle is
Fails to replace pages - when turned on
8th - 15th turns on! This allows more
Rotsya with protection implemented using
filling the 8th page with all sorts of crap.
   First, cut the paths coming from
the following legs on D48: 2.5 and 7. Here is our own
and the diagram:

   The ID7 chip deciphers the country number
nits and checks that the buttons are closed.
If the eighth page is turned on and on E0, E1
low level, then on the 15th leg appears -
Xia is also a low level that goes to
KP11. When the level is low, the country is connected
number, which is indicated on A0-A2, and when
juice, which is indicated on B0-B2. So about
everything works at once.
   Now I want to say thank you to Sergei
Romanov, without whom I have nothing
it would work out.
