||A style of game where the aim is compete either
against another player or the computer in a race around a track. Some involve racing cars
or motor cycles viewed from the driving seat while others show all of the cars and the
track from overhead.
||A portion of the Amiga's memory set aside to act
like a disk drive. There are many advantages, such as faster access times than to a floppy
or even a hard drive, and unlike the standard RAM Disk the contents are retained if the
Amiga is warm-booted (Ctrl-A-A), but not once the power is turned off. The main
disadvantage is that the size is normally limited to that of a floppy disk, but this can
also be an advantage when compiling files ready for output to a floppy disk - simply
transfer the file to RAD, and when finished, use disk copy to create the floppy disk from
Random Access Memory.
||A portion of the Amiga's memory that functions
like a disk drive. There are many advantages, such as faster access times than using a
floppy disk or even a hard drive. The only disadvantage is that the contents are lost once
the computer is turned off.
||The name given to the
RAM controller chip
found in Amiga A3000s, etc.
|RANDOM ACCESS MEMORY
||Refers to the memory used to store data and
execute instructions, and can be read from or written to in a random order unlike the
sequential access of say an audio tape. A 16 bit Amiga can have up to 9 Megabytes of RAM
(1Mb Chip and 8Mb Fast) while a 32 bit Amiga can theoretically have up to 1700 Megabytes
(2Mb Chip plus Fast) although less than 64Mb is normal. See also Chip
RAM, Fast RAM
||A picture comprised of pixels, such as the Amiga
produces on its monitor. Vector images are made up from lines, and are not used by the
||Mathematically calculating the colour of each
pixel on the screen as the point where a light ray intersects the plane of the screen. The
ray is traced back in time as it is reflected and refracted by the objects in the scene.
|READ ONLY MEMORY
||Refers to memory used to store data and execute
instructions which can be read from but not written to. Typically used to store static
data which does not change, such as the KickStart
||A term which broadly means happening as we see
it, but in many cases real time illustrates something more like a time warp (backwards or
just oh so slowwwwww) even with a fairly fast processor.
||Often used to describe a warm boot, but can
equally apply to a cold boot.
||May refer to the process of receiving data, but
is more correctly used in reference to pin 3 of the RS-232C interface, which is used to
receive the data being transmitted via a modem. The latter may also have an indicator
light labelled RD (Receive Data) to show when data is being received.
|REDUCED INSTRUCTION SET
||A computer that understands a minimum number of
instructions, as opposed to CISC processors. Program writing is more complex and more
difficult, but the programs run significantly faster. The exact opposite of CISC.
||The process of converting a graphic defined
using a mathematical formula into a recognisable image. The process is required for
virtually all 3-D Modelling Programs, as well as
Character Generators and Image
Processors. Be warned though because most rendering can take quite a while unless you
have an accelerator in your machine, and even then it might seem long.
||The 3-D graphics format created by Numerical
Design Ltd, a company which makes 3D rendering engines for hire. Software packages using
this engine can usually support writing the resulting image data in Rendition format. One
such package is Octree Software's Caligari Broadcast, while the ADPro Professional
Conversion Pack can be used to convert it to other formats.
|REQUEST TO SEND
||Refers to the process of a data terminal
requesting to transmit its data, but is more correctly used in reference to pin 4 of the
RS-232C interface which is used to pass the signal between the terminal and the modem.
Once the signal is detected by the modem, it will reply by sending a Clear To Send signal
to the terminal. This is only effective when RTS/CTS hardware handshaking is being used.
||A rectangular box that appears when the system
or the program needs more information from you. A requester usually contains boxes that
give you a choice of actions. To exit the requester, you must select one of the displayed
boxes, one of which will normally be `Cancel' which enables you to exit from a requester
without doing anything.

horizontally and vertically on the screen. The modes available depend on the machine being
used and the version of the Graphics chipset, as follows:

||A standard proposed by Commodore, where the
display format is independent of the software generating the output display that would
enable virtually any program to output to any graphics card or screen resolution including
any not even aviailable when the program was written.
||Acronym for Radio (or Reference) Frequency
Modulator, which is a device that adapts an RGB or composite video signal, so that it can
be used with a standard television receiver. Using RGB input, the RF modulator first
converts this to a composite video signal, and then encodes the composite video output,
combining it with an audio signal if desired, into a radio frequency signal that can be
input via the aerial socket of a TV or video receiver tuned to the corresponding
frequency. The Commodore A520 is such a device for the A500, but is supplied internally on
A600's and A1200's. Because of the encoding and decoding that is required, there is a
certain amount of signal and quality loss compared to RGB or even composite.
||Stands for Red, Green, Blue which are the
primary colours used to display images on the screen.
||A video display device where separate input
signals are provided for Red, Green, Blue, and sync, rather than the composite or
monitors used for displaying video generated images. The result is a clearer image but
even this depends on the horizontal scanning rate of the monitor. The 1084 is an RGB
analog monitor with a horizontal scan rate of 15KHz, which is able to display an unlimited
number of colours, as distinct from a digital RGB which can display only 16 colours, but
tends to flicker when hi-res mode is used. More stable pictures can be achieved with
multi-sync or tri-sync monitors.
||Connecting cable where each wire is individually
wrapped in plastic, but layed in parallel beside the other cables, much like a strip of
licorice. The cables can be soldered to the connectors, but they would normally use a type
of connector that simply presses into the cable, and held in place by a locking strip. The
primary disadvantage of this type of cable is the lack of shielding, so it can be
susceptible to stray signals.
Reduced Instruction Set
card which plugs into an expansion slot on the motherboard into
which other expansion cards can then be plugged, generally so that the
latter are parallel to the motherboard rather than at right angles to it.
It can often be used to expand the number of expansion slots available on

||Role-playing games differ from adventure games,
in that you get to define your character (or party of characters) at the beginning of the
game. You can often name your characters, (be they dwarves, fighters, wizards, whoever),
and you tend to see proceedings through the eyes of your character or party rather than
moving a character on the screen.
Read Only Memory.
|ROM KERNEL MANUAL
||Actually a set of manuals, namely "Includes
& AutoDocs", "Libraries" and "Devices" which describe much of
the internal workings of the Amiga, and the rules for correctly programming the hardware.
They are published by Addison and Wesley and are revised with each new AmigaDOS release.
SuperUser ID on a Linux or Unix system who can do virtually anything. In
effect ROOT, owns and controls the entire system, and is used to
administer other users etc.
||The central or main directory on a disk.
`root directory' is created when a disk is formatted. All other directories must be
created by you., either with the "MAKEDIR" AmigaDOS command, or copying the
"Empty" drawer and renaming it, or using the "New Drawer" menu item
under AmigaDOS 2.0 and above.
root directory (identified as "/") is the hub of a Linux or Unix
filesystem, and is the base of the tree from which all other directories
and files are linked.
||A standard for transmission of serial data
covering both hardware configurations and transmission parameters using a 25 pin connector
||A standard for transmission of serial data
covering both hardware configurations and transmission parameters using a small 8 pin
connector, found on the Macintosh and high-end video equipment.
||Acronym for Read The Flaming Manual,
(or similar) often used
in response to errors or problems that users might have where it is obvious they could
have helped themselves simply by reading the instructions in the manual.
Request To Send.
||A form of flow control for data transmission
which uses two of the RS-232 lines for signalling between your computer and the modem, as
opposed to adding special characters as used for XON/XOFF flow control. This method is
also preferable because of its speed and reliability.
