   Hi everyone!

   This is me - Romanov Maxim. Well
so I completed the long-awaited game, and even released her for 
sale in connection with what I had

some free time, and I
I decided to write an article about
Article S. Zonova in the "What
newcomer? "(ZX-Format # 1), most of all smacks of advertising, 
and reminded me of a certain interview with Mr. Zonov pages 
ZX-REVIEW. But the important thing is not to this - Zonov, 
advertising their commodity curse someone else and

Turns user into a dead end,
giving them fantastic opportunities for their product and does 
not indicate how much should be spent money in order to get 
these features! Yes, and whether they should have so it seems 
Mr. Zonov? In Most of them are over-

load, leading to excessive
Users spending.

   In order not to be unsubstantiated,
give an example.

   INTERFACE KEMPSTON MOUSE +
IBM PC KEYBOARD + ... Per se
mouse interface - it's good, Mr.
Mesons made like everything correctly,
- Interface understands cheap
passive mouse and expensive activity, which, basically, can not 
provide those dynamic features that provide passive. Someone 
could say: "Passive mouse - this is nonsense, but there is no 
search, and active - this thing! "Here we can say one thing: 
yes, we have active in the country mice received the most high

distribution (mostly in
IBM), due to the fact that the connection is not necessary to 
put the add additional maps such as

for BUS-MOUSE (passive mouse
interpretation of IBM), because most of the components is 
already a or more COM ports

multicards, and adding
excess iron makes a conflict. I had one
a friend who bought SOUNDBLASTER, and this blaster he
clashed with myshoy (serial),
Therefore, if the game required
mouse - a man cut off blaster
and if he wanted to play with music,
then had to disable the mouse ...
Insanity? But on the Spectrum of the
hardly anyone will wait. In general,
based on my observations, I
(This is my and only my opinion)
was not satisfied with the work
Serial Mouse (active) when it
small frequency of the survey works in principle fine, but when
increasing frequency, its dynamic characteristics of several
deteriorate. This is due mainly to the fact that the active 
mouse uses to communicate with

Computer Interface Type
RS-232, a rate of exchange in 1200
baud (depending on the type of mouse
transferred 3 or 5 bytes of data
which is sufficient for PC).
At this rate turns out that a second in interface passed in the 
best case 150 bytes, and they are sufficient

for polling frequency 50Hz (or less), but with increasing 
frequency (For quick drawing), you get the same result as the

at 50Hz. To better understand the
going a little dig
in principle of the serial-mouse:
after moving the mouse to the microprocessor in myshe received 
pulses account. Processor in the internal registers vychilyaet 
shift from the previous location and sends the line 
corresponding Code: 3 bytes for Microsoft mouse

(2 buttons), and 5 bytes to 3
PC-AT mouse (3 buttons). Should
note that the coordinates and buttons are transferred only when 
the state (physical) mice, either button or shift, say, right. 
From all this shows that at 1200 baud and frequency of survey

50Hz controller manages to give the processor valid
coordinates, whereas an increase in polling frequency, processor
will be issued to the previous location, because the old 
movement is stored in registers and the new has not yet managed 
to pass the due to the limited speed. Here

and got such a kind
jagged lines instead of smooth,
even with the increased frequency survey. Such a mouse can be 
compared with a long rope: if one

people will take up one, but
second - for the other end of the rope, and the second will 
start its fast pull back and forth, then up to the first reach, 
not all tugging rope. But if the rope was short, the first 
would have received absolutely everything fluctuations.


   Well, the passive mouse with the corresponding controller 
can modify the coordinates of the most clearly, regardless of 
the frequency survey, and the speed of movement

mouse (the maximum speed of movement of the mouse about 1.5 
meters per second) because it does not need twice to convert 
the coordinates. 

   Active mouse - the most popular and quite expensive
($ 8-15), and passive, much less ubiquitous, more
cheaper (remember that active is a juicy-chip microprocessor, 
and a passive low-cost logic (1-2 case)). I've seen super mouse 
for $ 15! K Also in the serial-mouse usually

two buttons, which is unacceptable for
Some programs, though at
passive mice can also have two
buttons (except the Soviet - in
them, I've never seen less than 3
buttons).

   Now a few words about PCKEYBOARD ... Klaviaturka itself bad, 
I'm against it, nothing am. But I do have an opinion

about the appropriateness of this
attachment (attachment not so
small, but $ 15-20). Sure, 101 / 2 keys are better than 40, and 
better than 58. What could be them! One disadvantage - on the 
buttons than the standard alphanumeric set of nothing! It can 
not be! Because it at PC over and is not necessary. BUT! Here 
you not there! At Spectrum accepted

some other ideology keyboard than on other machines. I
not about the fact that on the Spectrum keyboard of a different 
color or shape, and about the fact that the buttons in addition 
to basic character set

there's Thong operators
(PRINT, RANDOMIZE, COS, STEP and
etc.), which was not found on pisyushnoy
keyboard. Of course, everything
mozho get used to, but why do
inconvenience, and then with a haughty air to it to adapt? No 
doubt many of those who put currently pisishnuyu keyboard, put 
it deep thought (or zombie advertising and word "IBM"), for, 
say, in IS-DOS (text and redatory

etc.) for them (unless they
nothing else involved) certainly nebylo Labor remember
location button "R", "J" or
"L" with enterom ... But others who
bought without thinking, had
encounter problems such as:
long to find the right operators, and
mathematical functions in standard BASIC (Interestingly, in
What else can perform a calculation?) are confused on a regular 
basis keys CTRL, SHIFT, ALT; also

there is little inconvenience rather big in size
keyboard (keep it on the lap uncomfortable, and the board is 
still inconvenient). Mr. Zonov for greater competitiveness, or 
be bought for more, it would be nice to make nakleechki keys 
sinklerovskoy marking, and it turns out you bought a 
super-calculator, but It is nothing other than digital buttons

not signed, and that's to guess where
is the most desired feature for
which are bought and all that
calculator.

   Well, sort of with keyboards
understood, and came to my
favorite subject: Disassembly of the
interface as a whole!

   Start small. Mr. Zonov
poses a huge, a really fat plus on the contrary, that the 
interface can emulate a mouse any joystick, plus a smaller

opposite the juicy features AUTOFIRE. In my opinion emulation
Joystick - it's yesterday
(I wonder he tried to Zonov
something to play with emulation
Joystick?). Gone are the days
When purchasing a single-yourselfers
where a mouse from the EU, and inserting
in it a couple of chips podtseplyali
it instead of a joystick, with the wild
pride on his face. Ah-ah! Not
only direct and diagonal now
they could draw in detail in
ART-STUDIO! But after a while
and came to a more "normal" mice. A typical example: "KEMPSTON
MOUSE "too connected to the port
KEMPSTON, but worked on the principle of
similar to today's mice,
elementary part has been simplified
to a minimum, basically, its role
performed software. The disadvantage of it was a small number 
of programs. Or rather there was one program

"MOUSE STUDIO" (C) DEVID, and most important drawback was
the principle of consultation. Processor had to spend nearly
all his time to the processing of signals from the mouse, so 
about any adaptation to her game is not could be no question. 
But just time, and appeared the most successful of all 
previously seen interfaces: KEMPSTON MOUSE INTERFACE 
(compatible, among other things, with a proprietary interface, 
and hence the program). In Due to the fact that the above

interface had a low-cost, easy installation, a
It has been adapted many
programs such as gaming and
system. Are almost no programs that are loading
user-sigh would be: That would be
here insert a mouse! Good programmers have long been all 
rebuilt, even a bit overdone, and adapted that a mouse

It looks puschim marasmus (not
I will call someone and that). And now
Mr. Zonov, a year later, says
that his mouse is good because
emulates a joystick! (FU!). Undoubtedly, we must pay tribute,
that the interface is zonovskom
a useful function as
AUTOFIRE. BUT! To this end, as
to emulate the joystick should ALWAYS buy the keyboard!
Otherwise you can not switch
mode! It's like that: you go
to the store to buy a bike with the clear intention of riding 
on it. Having come into the store and pay money (a lot, bike 
after all) you are given some reason scooter, besides, without 
wheels ... On a normal question "how to

this, pardon the expression, to ride? "you reasonably respond,
that, say, you can buy a wheel and pedals with the seat for a 
fee, and get a bike ... The same and Zonova. Buy a mouse 
interface ($ 15) to it very mouse ($ 10), and if

completely itch - keyboard
($ 18) to emulate a joystick, and have promised AUTOFIRE.
In general, when a simple calculation, those facilities that 
offer Mr. Zonov (15 +10 = 18 $ 43!) poured into 43 (yes, 
forty-three) dollar. If we translate this into

Ruble, then all the hair vylezut!
Almost as worth paying for Scorpio. Our mouse is entirely
$ 10, this includes the interface
mouse, drive, and warranty! Try to compare 43 and 10 ...

   On top of blatant
lie, in order to mess around in the article was issued that
our mouse, they say, can not be connected to the scorpions! You 
can! Connect quickly and easily! And after connection through 
the system connector, you have the system connector

remains free to further connect peripherals. K
other computers connected
easy, most importantly follow the small instructions, and if not
help - please contact your place
acquisition interface! Generally,
I am a little riled, what
this entire interface has been named
new development. Mouse interface for over a year as no new
Keyboard - too. Such a mix
reminds me of what is happening
Today in the soft sector (software). Come
"NEW" games, mostly 19891992, at least - 1993 edition. C
they come pretty old
game, but a new design (in
loading), and inserted with the music ... However, in Zonova: 
old thing old thing + = steep

nove! Reasonable to assume
that after some time, Mr.
Mesons come up with something new
(Or steal it, as always somebody else's idea, immediately 
forgetting someone), or find some - any old-style light gun,

and blowing up of impossibility,
crossed it, let's say with your mouse manipulator, and write
another article, where he will tell you how good lie on the 
couch with a gun from the Dandy, and shooting across the screen 
to write programs in BASIC. Or not in Basic, that someone like 
... Using his super-new interface ... 


   On this end let
