  AMIGA vs PC



   Hello, dear readers. We are very pleased that at
This time you looked at this interesting section of our 
newspaper. 

   Many of you after reading the previous file numbers ZX-PILOT,
probably had many questions about this unique,
friendly and easy to use PC - AMIGA. Today
we will acquaint you with the basic features of different models
Amigo, a Mad Max from the ZX-Format'a will try to answer some
your questions.


   A500 - the most common model, which replaced
A1000 in 1987 and produced until October 1991. As
asked one user PC, - "The keyboard can see, and where he
computer? "himself fit inside your own computer
keyboard. In a typewriter 512K of memory and processor M168000 
on 7MHz. Hard drive, and most other devices dock

side of the connector system bus. Accessory Shoe
intended to set 512K of memory. Built-in (880Kb)
3.5''floppy drive. Version of Kickstart 1.2 or 1.3. Adding 
another 512K of memory gives the car a so-called "Slow" (slow) 
memory, can be add up to 8 MB of fast (fast) memory, which

CPU runs at maximum speed.

   A2000 - virtually the same as the A500, but the system unit
separately from the keyboard. Intended mainly for those
Amigo users who wish to expand their opportunities,
without going outside the system box, which establishes the
expansion slots of the system. Version of the 2000C has a 1MB 
memory Standard postavke.Postavlyaetsya with the hard drive as 
standard configuration.


   CDTV - the combination of A500 and laser disc player. Not
widespread, despite its original
related nadezhdy.Predshestvennik big game variant
Amiga CD/32.

   A3000 - a professional version of the Amiga. Central
68030/25 MHz processor. The first machine with a KickStart 
version 2. System unit separate from the keyboard. Gorgeous, 
though an expensive computer with a built-flicker suppressor

(Ie node suppress unwanted screen flicker when
interlaced).

   A500 + - improved version of the A500, produced from October 
1991 by June 1992 Shipped with megabytes of memory, an improved

soprotsessornogo option set, built-in clock and Kickstart
4.2 and 2.1. Very nice replacement for the A500.

   A600 - released in June 1992 as a model, come on
replace A500 +. The smallest (in size) of all the Amigo.
Keyboard curtailed due to the absence of additional keys.
Instead connector system expansion has PCMCIA - slot,
intended for connection of flat cards, which contain
usually 2 or 4 MB of RAM. Soprotsessorny set
and memory - the same as that of the A500 +. In contrast, 
provides installation of internal 2,5''IDE hard drive. After 
nakotoryh alterations can be set and 3.5''drive.


   A1200 - the first of the "real" Amigo. Has the so-called
AGA (Advanced Graphic Architecture - Advanced
graphics architecture) soprotsessorny set to radically
improved capabilities. 32 - bit processor M68EC020 (14
MHz), many new high-resolution screen modes
(Maximum - 1448h566), palette of colors to 262000
16 million, 4 types of video outputs (analog RGB, TTL, RGB,
low frequency and radio frequency PAL PAL), a great OS 3.0 and
etc. Comes standard with 2 MB of memory, but if you do not want 
to just playing with toys (which, incidentally, on Amiga 7000)

it is highly desirable to add an expansion card with at least
4 MB of fast-memory, then can rightfully consider themselves
vladelzhem already serious kompyutera.Imeet internal 
IDE-connector to connect 2.5''hard drive (you can after some

alterations to install and 3,5''). The best option home
PC today for those who are not accustomed to throwing
money.

   A4000 - a professional version of the "real" Amiga. Processor
68040/25.Kstati, Motorola of the inherent modesty, does not 
mention that 68,040 runs at twice the internal clock

frequency, ie actually 50 MHz. Comes with a chip-memory 2
MB + 4 MB Fast (limit - 128 mb). Memory can be expanded
by standard SIMM-s. Machine in the initial state is in 3
times more expensive A1200, although the graphics and sound 
they are the same (if not give light weight A4000 different 
extensions). Ideal for computer the owners of cable TV studios, 
artists, composers and programmers.


   In the near future we plan to release a more powerful
Amiga computers based on RISC-architecture. Although
that is quite enough. In addition, there is a wide
choice of accelerators uvelichevayuschih performance
existing models in standard configurations.

   VDV> You cite a lot of technical harakteristik it
well, but it's taki znat would like to view the Knower of 
people in sravnenii Amiga with other kompyuterami and best 
pristavkami in for games (it is no secret


   MM> Best - Best pristavki worth the money, I am not 
referring SEGA, SUPER NINTENDO, DENDY ... Besides kartridzhi 
(some gamers can not stand to see for some time PLEASE

WAIT, LOADING ... with CD-based consoles) are nemalo, although
multi - millionaires samy raz. Nay, some pristavki
priblizhayutsya on graficheskoy performance of SGI, but they
only pristavki ... ;)

   VDV> that almost all za rare exception, pokupayut computers
primarily for razvlecheny) a tak HOW Amiga-media
computer, then to him it is primarily prvda not it?
Itak, where the same all-taki better grafika (not animatsiya, a 
kartinki)? A takzhe in sravnenii Amig'i with Seg'oy (tak HOW I 
have no idea sklko flowers at SEGA, but as the judges saw and 
if I znal opinion spetsialista, I could about what predstavit 
takoe Amiga). 

   MM> Ha date, there are 3 graficheskih Architecture
Amiga. With emphasis sdelan nA samuyu last, kotoraya
obespechivaet compatibility of top-down with more starymi
realizatsiyami. Here they are: OCS-Original Chip Set, used for 
long nA first time mashinah and had 32 color registra that

allowed otobrazhat kartinki in 32 Colors (without ispolzovaniya
Copper), a tak same treatment HAM6, which otobrazhal nA ekrane 
4096. Palitra imela razryadnost 12 bits, which is prevalent 
made in its all 4096 colors. Later in the OCS was dobavlen mode 
EHB - or Extra Half Bright, which allow otobrazhat 64 Colors. 
Tak HOW Register ostavalos 32, additional 32 Colors poluchalis

dividing the intensity of primary colors nA large screen (Half 
Bright). OCS obespechival razresheniya srokam to 320 in 32 
Colors and HAM6, and EHB, and 16 colors in razreshenii 640, on 
verikali razresheniya from 200 to 512. Chip memory is the 
volume was increased za period modifikatsii OCS with 256K to 
1MB. 

   In 1990 byla vypuschena A3000 with slegka Modified Chip Set
which nazyvalsya ECS (Enhanced Chip Set), it was all
HOW tak about the same, and OCS, but he could adresovat 2MB 
memory is and was Ultra-high razreshenie 1280 on the line with 
4 me tsvetami.Nekotorye changes kasnulis Blitter (heart 
grafiki), which could now peresylat gorazdo large memory is 
chasti za raz. 

   With the advent of A4000 in 1992, which was predstavlen samy
advanced since sozdaniya Amiga Chip set. It was the AGA.
Advanced Grafix Architecture, was a revolutionary advance 
skachkom with respect to ECS. It poyavilas 24 bitnaya palitra 
(12 ECS) and in any razreshenii could ispolzovat 256 colors and 
a new mode HAM8, allowing otobrazhat 18 bit grafiku (262144

Colors at the same time in any of razresheniyah palityr 16. 7
million.). What kasaemo games, then in the OCS and ECS for two
nezavisimyh planov game was available for 7 colors
(Dual Playfield, Each time a plane can be a game to 7 colors)
a in the AGA this pokazatel increased more than large screen 
raza! 16 colors in the field of play. It sounds frivolous, but 
if you still add an some clever tricks with Copper, then the 
colors will be more and planov more, tak to krayney least be 
kazatsya. For convincing, go and look at somebody from friends 
igruhu (NA rasschitannuyu OCS) Lion HEART (Lion Heart). This is 
a typical HOW klassichesky example without a huge zatrat (PC) 
sdelat all plavno and with a bunch of planov.


   Generally, if the right in the forehead, then in principle 
staticheskie kartinki nA True Color sVGA and A1200 are 
identical (anybody can tell HAM8 of 24-bit?)


   VDV> A takzhe for music, I would like znat one:
HOW is proigryvanie Moose coprocessor muzona (HOW nA
Speccy - nado vsegda kidat dannye it new or is there
kakoy a better way, naprimer muses. sam, etc.
takes the following dannye, a CPU only izredka kidaet his 
Address New muzona?)


   MM> Paula - the voice of the Amiga. Rabotaet extremely 
simple (I of sound). There are 4 kanala direct dostupa to 
memory is (DMA), by which carried vyborka of memory is with a 
certain period ocherednaya portion dannyh. Vyborka dannyh sound 
has a greater priority than the processor, a time of sampling 
must end nA kazhdoy line television rastra. Za raz vybiraetsya 
2 Words (One word 16 bits). Period for kazhdogo kanala 
programmiruetsya potsessorom through registers Paula. In 
addition, nA Each time kanale there is a volume control 
razryadnostyu in 6 bits, along with 8 bitami zvuka daet 
dinamichesky diapazon 14 bits (from a CD 16-bit). 
Programmirovanie tunes by the processor, and zanimaet lot of 
time. Tak dazhe nA 68,000 with 7Mhz modules skompilirovannye 
TrackerPacker 3, proigryvanii zanimayut only 3 rows rastra (if 
schitat on hakerski). 

   VDV> Tak, going dalshe: no secret of the fact that many of 
the range, what to buy - AMIGA 1200 turbo or Pentium with a 
bunch of pribambasov and I HOW predstavitel takoy rasy, soul 
gravitate to the exotic Amig'e, but constantly see new GAMES by 
IBM (tipa FANTASMAGORIA, etc.) and want uznat, a vybrav AMIGA, 
get-I nA it is not ostanemsya, we again otstayuschih - HOW nA 
Speccy (Prosba not vozrazhat, HOW is not bitter, but that's all 
pravda ponimayut.)


   MM> Amiga Commodore after krizisa vstala nA feet, and not
hurries to the tomb. Ha she writes programmy, razrabatyvaetsya 
iron. All that nA Speccy already davnym - davno not delayut. In 
connection with the This burying Amiga ranovato ...


   MM> In principle, the same samoe unlikely, we can obtain 
gorazdo better. Of course, nA bare A600, or A1200, it is 
unlikely to be rabotat.


   VDV> Tak glavny question here is: Tough Games still write 
under Amiga and IBM (with the worst kachestvom), or just under 
the IBM? 

   MM> Write and by then, and under another, glavnoe elsewhere: 
in a nas strane malo who zanimaetsya dostavaniem softa. A if 
anyone zanimaetsya, the meager masshtabah, and his vkusam. At 
the HOW time for the PC all and sundry prodayut software that 
not having appear nA prilavkah Zapada already popadaet to 
nashim lovers. But takoy situatsiya long stay can not. All 
repeat HOW to PC. A few years nazad, all begali with XT and 
dostavali something HOW Games vesma questionable kachestva ... 
Wait and see ... 

   VDV> And another thing: I do a lot of slyshal programmnye 
emulators IBM, tak Here's HOW the same emulated SVGA grafika 
and emulated, whether SOUND BLASTER?


   MM> Yea, there are emulators programmnye PC. Naibolee worthy 
of nA them today is PC-Task 3.1 (because of the above

circumstances do not know whether the next version). It emulates
Computer nA baze 286 protsessora without FPU. Tak also emulates 
sVGA up to 2Mb, and mouse. Thus do the same is able rabotat 
napryamuyu with PC HDD. Author PC-TASK obeschal continue 
razrabotku add an emulation 386 and 486 protsessora. Tak we are 
waiting, sir. A nA A1200 with Blizzard IV 1230 nA 50Mhz it over 
the dough (CHECK IT) emulsion 286 nA 30Mhz. Naschet Blaster not 
pripominayu, although it may be. In addition, there are nA 
Amiga More kucha other emulators. Naprimer, one of 
vydayuschihsya it emulator MAC. Ha A4000 with 040 emulsion 
Quadra900. 

   ZF> According to recent reports there has been the PC-Task,
supports 486.

   ZF> According to the latest information - even Pentium.

   VDV> Next question: kakoy monitor needed Amiga.

   MM> K Amiga fits any monitor, either on Spektruma
(Dazhe TV) or sVGA. A bit disappointing, but may sVGA
rabotat only under operatsionnoy system, while HOW
usual monitor anywhere. There is a way out: Multisync with 
chastotoy rows of 15 Khz and above. It will rabotat anywhere 
and in all rezhimah.


   VDV> Well, the last and samy glavny question: where it is 
sold formally (in Moscow, of course, will not go - I za her in 
St. Petersburg, Russia)? 

   MM> Poka we sami za Amiga we go to Moscow. We go to the firm 
SAKO to address: 1 st Dobryninsky lane., 8. Tel / Fax: (095)
