Q. Can AMIGA work with
third-party software
computers?

A. The Amiga, there are many
emulators on other platforms. In
including - even the Amiga.
Practically, there is enough quality ZX Spectrum emulator
(Which would be very useful to users of the platform, passing 
on the Amiga and do not wish to be in a totally unfamiliar

environment), IBM PC 80486
Pentium (realizing the dynamic translation code, which sharply
improves performance)
Yamaha MSX-2, Apple-2, Atari
VCS / XL / XE / ST, Commodore-64,
Amstrad, GameBoy, BBC, TRS-80,
Sinclair-QL and a variety of less
famous computers and consoles. Will soon be ready emulator
BK0010/0011.

Q. Are there emulators for the Amiga
other platforms?

O. UNIX AMIGA Emulator (UAE) exists for almost all
platforms, including Amiga itself.
Available in source code
in C. Emulates the OCS chipset
(1984), requires insane
high speed processor for
more or less normal operation
(At a good workstation). Nevertheless, in many
where he is unable to
to reproduce the graphics and sound,
completely identical to the original.
Emulator ECS and AGA, ie
modern Amigo does not exist.

Q. What is "datataypy"
(Datatypes)?

A. The Amiga operating system
starting with the third version of the integrated
mechanism for recognition of various
types of files and work with them.
Thus, for example, the graphics editor is not necessary
know about all graphics file formats - the presence in the 
system datatypes correct format will make it possible to 
download them. No does not prevent you from inventing

own data format, write to the OS support it - and
Most modern programs
begin to understand it. Naturally, datatype - means not
only for working with graphics:
supported and sound, and so on.
In addition, the datatypes are already
built-in support for viewing
files, and system utilities
Multiview allows you to see
Any files, of which "knows"
system.

Q. What is CyberGraphX?

A. This is a complete rewrite of several libraries with AmigaOS
to support the cards that implement all the standard graphics 
system These maps and supporting new features (modes 2, 3 and 4

bytes per pixel, any organization of video memory). Under each
CyberGraphX ​​supported video card is a special driver.
Currently, software
CGX interface is the de facto standard.

Q. What kind of monitor for podoydet
Amiga?

A. Almost any. Firstly,
AMIGA 1200 comes with a cable for connecting to a TV, so start 
working You can do without a monitor.

Even if the monitor - Toys on TV with a huge
diagonal look better. There
three ways to connect to a TV: the high frequency (supplied 
cable connects the output RF Modulator Amiga to the antenna 
input on your TV and tune it to the desired channel), the low 
frequency (output Comp Amigi connect to the video input on your 
TV) - in this case, the sound should make a TV or amplifier 
separately, and RGB - for example, the firm CONDOR SELL an 
adapter for SCART. If you have with vremen BC, Spectrum and 
other Soviet computer technology

remained monitor type MS6105,
MS6106 and the like - they too will work like any
another monitor with TV
razvertki frequencies. Work well on monitors ATARI,
COMMODORE and most other
eight-bit machines. Permissions
thus obtained are: 320,
640 or 1280 dots per line, and
256-280 lines vertically.
When using the so-called
Interlaced razvertki can
get up to 576 lines - but
In many cases, the image will flicker (this mode
used in television).

     Their most best option for
Amiga - the so-called
Multisync monitor. Such a monitor
not only supports television frequencies razvertki, so you can 
install 640x480 resolution, flicker-free type. Specifically for 
the Amiga by Microvitec produced 14 and 17-inch monitors, which 
have this possibility, in addition,

Similar monitors produced a
produce some of the other firms
(NEC, Toshiba, Nokia ...). Many
Multisync-mode and allow you to set Super72 (800x600 and
more). If you are on the Amiga is any video card, then
Depending on the capabilities of the monitor can be used
and high resolution. There are
another option - use
SVGA monitor on the IBM PC.

B. There is an old A600. Q: Can I connect to SVGA
monitor?

A. Yes. Differences ECS chipset
AGA are, for example,
that at VGA frequencies can be
will only work in chetyreh
colors (for AGA - maximum 262,144
from a palette of 16 million). Besides
- Very slowly (with the same
fast as in 16 colors).

Q: How sound input into the computer?

O. This is a sampler
LPT (8 bit). Sold, for example, the firm Sako. For the needs of
writing MOD / etc and Russification
lusty cries of the protagonist
in your favorite toy of this
quite enough. If you need
sereznaya work with sound, need to buy a sound card under the 
bus PCMCIA (Aura) or Zorro

(Toccata) - they allow you to work with 16-bit sound.

Q. Will work hard disks
more than 500 megabytes?

O. Will. This restriction
peculiar only to MS-DOS.

B. It is known that one
IDE controller can hang 2
devaysa. Is there any way to any
standard A1200 hang 2 IDE
screws and IDE CD-ROM?

O. No modifications - you can not. When
special connection
device is connected
possible. Also, there are
things: an additional PCMCIA IDE
controller for CD-ROMs, board-to-IDE adapter with at SCSI, and 
SCSI controllers. In the presence of

SCSI-controller can connect two IDE and seven SCSI
devices.

Q. Is there an analog pisishnogo
ARVID?

A. Yes, said VideoBackup.
Record a video idet via standard video machines, reading - 
through RS232C. Obem information on one tape is not so large - 
about 800 Mb, but the cost of the device on compared with Arvid 
minimal - there is only one chip ;-)

Given the small size of the software
on the Amiga than pisishnym, particularly differences in 
general and no. But in recent years in connection with a 
horrible podeshevleniem CD-ROM the most convenient and 
expeditious "archival" storage become CD-R (they are also 
CD-WORM, CD Recordable, CD Enregistrable) -

in common parlance "gold" discs.

B. I want to connect a CD-ROM.

O. Connect any IDE ATAPI
CD-ROM. A proven work
all except VERTOS 300. Clings
slave to the IDE hard drive. If
you have a SCSI-controller is better
put the SCSI CD-ROM.

B. I want to listen to Audio-CD.

A. No problem - "players" in bulk.

B. I want to watch Video-CD.

A. There is a software MPEG Players
files (several) and CDXL
(At least one), requiring
A VERY fast machine - the full-SVHS quality requires 68,060 and 
CyberGraphX-compatible video card. There hardvernye board for 
SCSI (Squirrel MPEG), and Zorro. In this case,

speed is not critical.

B. I want to burn CD-R.

A. No problem. There are all the necessary software - you only 
need to buy a SCSI-controller and a CD-recorder, for example 
Philips. And you can just go to the firm Condor, and you would 
have a moderate amount will record a CD directly from your HDD.


B. I want to "rob" music
Audio-CD.

A. If the CD-ROM it allows
(Eg, ATAPI IDE Panasonic
CR-572B allows precise), using, for example, the program
TRKDownLoad from package
atapi_p'n'p. The sound is reset
to a hard drive with any digit (16bit, 8bit, ADPCM),
Stereo / Mono on request, with any
sampling frequency. With the program from the AtapiCheck
same package, you can find out the possibility of a specific 
plug in Model CD-ROM.


B. I want to listen to the received
soundtrack, or just WAV-s.
Heard that bit Amiga
audio output of 8 bits. What will
quality?

A. Bit audio output Amiga - 14 bit. Of sixteen can be 
distinguished, but only if very hard work. To play the sound 
can be used For example, a program of Play16, understand the 
format WAV, AIFF, IFF, and just RAW (only sound

data without the header). Maximum sampling rate
Sound - 60 kHz, is
twice the frequency of horizontal
razvertki monitor (the sound is selected from memory by DMA 
during the return beam). 

B. I want to hear not only the MOD,
but S3M, XM, MTM, etc.

A. To your health. Delitracker,
PS3M, HIP, and many other players. But - the more channels
the more quickly you need a car.
68030/50MHz quite enough. Although
eight-more or less plays and unextended A1200 ...

Q. And as with MIDI?

A. The best quality option - to buy and connect
WaveTable-card from the PC (eg,
YAMAHA DB50XG) - a subsidiary
boards that are "hung" on saundkarty PC. Connects a
board through a serial
port. There also can be connected
any synthesizer, which has MIDI
interface. With a few worst
quality MIDI music can be listened to, and software, with
program GMPlay (but it
critical to the speed of the machine).

B. I want to write music myself. In chem
it's better to do?

A. If the music is written with a view to
"Insert" ee in any toy, demoshku etc. - Better
ProTracker-e. The reason is simple -
4-channel music is played
hardverno without taking time
machines and without interfering with the main program. If the 
goal - to write music As such, the best option - Symphonie Pro. 
255 channels 16-bit audio with the ability to

recording sound tracks for a CD. If
there is a good synthesizer with MIDI
interface, you can use many types of sequencers Bars'Pipes.

Q. Can you work with disks formatted on a PC?

A. Of course. All necessary
driver is in the distribution
Workbench. To do this, click on the icon PC0 Directory
sys: storage / dosdrivers, or give
command mount pc0: - that in general there is one and the same. 
Read, written, formatted disk at 720 and 800 kb.


Q. How have floppy 1.44mb?

A. There is a special two-speed drives, which supports this 
mode. Transform an ordinary PC HD-ROM drive in a two-speed can 
be at "Condor". You can also buy the A1200 with the already

redesigned drive. But in
Currently diskettes as the storage medium itself is almost 
exhausted, and this is IMHO simply irrelevant. Historically

standard on the Amiga became floppy double density, and 
exchange with PC through such a floppy disk and runs

so.

Q. Can I read CD-ROMs
from the PC?

A. Yes. CD-ROM format
standard, and is called
ISO-9660. There are two varieties - the "castrated"
8 +3 filenames, tyazhelym vremen dark legacy "operating system" 
MS-DOS (Level 1) and with normal, up to 30

characters (Level 2). Both that and more - great read.
There are less common formats - for example, HFS on Mac. 
CacheCDFS to read and such discs.


Q. Can you "lug" soft on
hard drive, as is usually done on a PC?

A. Of course. This is done
exactly the same.

Q. Can I work with a hard drive formatted on a PC?

A. Naturally, the truth will not be
read HPFS / NTFS / etc sections -
only formatted
MS-DOS, Windows 3.x/95/NT or
OS / 2 formatted FAT.
