    Hi 2 all! Asked me
emphasize an article in this
magazine. I must say that it is
my first article, and how it
successful or not - to judge you.
Well, Well, let's go!


    It's about sound
map GENERAL SOUND. More precisely,
about its connection to your
typewriter. I will not paint
the pros and cons
GS, I can only say that I have
next to him for a while
was a Pentium with a map
SOUNDBLASTER 16/AWE32. Sound
Of course, not bad, at least
compared with SOUNDBLASTER PRO
(Real suxx!). So, when
comparing the quality of sound
one and the same hardware-
(Muztsentr SONY 28WX2) GENERAL
played a lot cleaner fashion than
SB16/AWE32 by IMPULSE
TRACKER 2.14. Maybe it's my
subjective opinion, but nobody
of those present at the same time
pc-Schnick anything bad about
sound quality is not said.


    But back to our
sheep. GS is connected to the ZX
is not simple - but very simple:
only 17 wires. And
if you Kay, Scorp, even
solder does not have to -
SYSBUS (PLUG 'PLAY;) I
Profi. SYSBUS - too
present and even the type, as
y Scorp / Kay. But there is one
"But." This signal IORQCE, he also
OUTIORQ, he also IORQ, etc ... He
in the idea of ​​blocking ports for
access to external devices.
I watched an interesting picture:
OUTIORQ, all of the
Profi + v5.02 was not named in the
Indeed, and here, the other on
Profi v4.xx was all
normal. That had to be
strictly in accordance with
Instructions to withstand the 20 th
foot wedged in the processor and
350-400 ohm resistor gap.
After that, the signal SYSBUS
IORQ became OUTIORQ, and
IORQ had to pull
wiring.



               Adrenaline

            distortions can

            try to formulate
approximated signal via an inverter
LL1:



    Although the fine resistor
copes with the incumbent on
his task. Do not overdo it with the length of wires from the ZX
to GS. The shorter they are,
so it will be easier. Of course, in
first comes to mind the idea of
solder the 8-bit slot, but
If you look closely, you can
solder GS and SNP64. Here at
I just did, and
GS is included in SYSBUS
and no one interferes. Exit
You can try to mix
exit AY, picking up
resistors, but for the best
qualities necessary to make switch.


    And another point. Catering to GS
better result apart from the
power source. After all,
second computer is almost
ought to be with him. Here
another problem - MOD'y healthy
painful, sometimes up to 450k - a mod
on the disk. Well, where is Dry?
That raises another issue
Winchester. But this in
next time. Only here
pity that only Riff Tracker
to 128k memory in GS.
