   Hi all zhelezyachnikam and all
the rest! Today I offer you
very Kulnev shemku one devaysa. This
the so-called uskoryalka and Lagsters
com. Who is it for you understand a little
later. To collect this pribambas you
need:

   - Three-way switch;

   - Three wire length so centimeters

     20;

   - Well, as usual, a couple liters of vodka and

     pickles.


   Thus, the scheme:

                             (1)

       to the 25 th leg Z80 o

                             /

       to the 29 th leg Z80 / (0)


       to the 16 th leg Z80 o

                             (2)


   And now a little explanation. Mode
NORMAL - closed contacts 0 and 0 (or rather
nothing is closed) switch is in the middle position. Comp works
as usual.

   Mode FAST - closed contacts 0 and 1.
But it's not TURBO. Such a thing happening:
all procedures that depend on IM2
rush to the free processor time
where Z80 is waiting for the arrival of an interrupt. All
other procedures (not hanging on
interrupts) are ignored. Personally, I
Use this function to scroll
Digital Muse or demos (when it is necessary
scroll through some tedious FX) ...

   Mode STOP - closed contacts 0 and 2.
PC just simply stops its
work, but does not hang. You may ask: A
where you can apply this mode? I you
answer: Imagine that you owe and
resistant, for example, play some
Gamez and suddenly you urgently need to
telephone and how to do evil no buttons
Pause ... Well, catch up!

   Well, that's all ... Bye.


  P.S. only 4 magazine 'Demo.or.Die'!!!
