VIDI VIDEO DIGITISER

INTRODUCTION

VIDI is a video -frame grabber/digitiser specifically designed for
use with the Amstrad CPC range of computers.
With this package, it is possible to capture a picture from any 
standard video source, camera, video recorder, even other computers. 
You may then save this picture on disc or tape, produce dynamic 
effects, manipulate the picture or re–display it on your CPC computer 
screen.
Pictures can be grabbed in MODE 2 (hi-resolution, 2 shades), MODE 1 
(med-resolution, 4 shades) or a special 16 shade MODE O synthesised 
picture.
VIDI contains its own CRT controller and 16k of video RAM enabling it 
to capture a moving picture at over 6 frames per second.
A ribbon cable with dual expansion connectors connects VIDI to the 
computer. A suitable video lead is also supplied, fitted with RCA 
(phono) and BNC (video) connectors.
Software is provided in two forms, an interactive control program and 
BASIC extensions (RSX's) for simple control of the sophisticated VIDI 
hardware.

CONNECTING UP

1. Ensure that the computer is switched OFF.
2. Attach the end of the VIDI ribbon cable to the expansion port of 
   the computer. See   Fig.l,   or   Fig.2   and  Fig.3  opposite.
   Care should be taken not - to connect the ribbon cable upside down. 
   Vidi must be connected-so that the ribbon cable is at the bottom 
   and the  duplicate  edge  connector   is   at   the   top.
3. Connect the phono end of the video cable to the socket on VIDI 
   and the BNC video plug to the VIDEO OUT* socket on your video 
   recorder or camera.
4. If your VIDI software is on ROM then insert this into a free
   socket in your ROM box as  detailed in its instructions.
5. Switch on your video equipment.
6. Switch on your computer and if fitted, the VIDI ROM will announce 
  Itself. If not insert the Disc or Tape supplied with the package 
  and Type :-
  RUN "VIDI  for Disc/Cassette users 
   or |VIDI  for ROM users. < | is   obtained  by using  SHIFT  and @ )
7. You should now be watching Digitised pictures on your computer
   screen! - if not read the 'Trouble Shooting' section.

THE SOFTWARE

TAPE: Side A of the cassette supplied contains the main VIDI command 
      obtained by typing RUN"VIDI". This is an interactive program 
      allowing complete yet simple control of the VIDI hardware. 
      Side B of the cassette contains the seperate commands to allow
      you to develop your own BASIC software using the advanced 
      features of the VIDI hardware.
DISC: The same two main parts of the VIDI software are on disc and 
      by Typing :-
      RUN "DISC, you will be given the following menu:
                 1.. Interactive VIDI command 
                 2.. Other RSX commands
      To select the correct option, you should press the relevant 
      key, 1 or 2. Alternatively, instead of RUN"DISC type RUN"VIDI 
      for the interactive program or RUN"RSX for the seperate RSX
      commands.
ROM: The ROM software offers all the functions of the |VIDI command 
     and the RSXs without having to load in' these parts individually. 
     You will find that using the ROM is much more convenient than 
     cassette or disc and frees more memory for your own programs (see 
     appendix A for upgrade details).

Using the |VIDI command

The software supplied with your VIDI video digitiser is contained in 
RSX form. The most comprehensive of these RSX commands is IVIDI and 
this is the one we shall start with.
At the bottom of your screen there is a MENU, this features a line of 
commands, one of which is highlighted (the GRAB option to start with) 
by a white bar, or cursor. To move this bar, we can use the left and 
right arrow keys on the keyboard or joystick.
If you move the cursor left or right you will see it select in turn 
each option. At the edge of the screen it will 'wrap around* and
appear at the other edge.
When an option has been selected, the option values may be changed by 
pressing the up and down keys on the keyboard or joystick.
1. The Brightness control
Move the Menu bar to the 'BRGT-07' option. This is the software 
brightness control and its range is from O to IS. As this value is 
increased or decreased the picture will become brighter or darker 
accordingly, with 15 being the brightest.
2. The Contrast control
The contrast control, 'CONT' is operated in much the same way as the 
brightness. Increasing the contrast will give a bolder, more defined 
picture consisting of less intermediate shades. Similarly, lowering 
the contrast results in an increase in intermediate shades and a less 
defined picture, just as the contrast on a normal TV.
3. The picture position controls
A normal TV picture is slightly too large to be displayed on tlio 
computer screen, instead we look through a window' onto this larger 
area. The picture position controls allow us to scroll this window 
over the TV picture.
It is possible to adjust the horizontal and vertical positions of the 
grabbed picture by changing the values next to the up-down and 
left-right arrows. Moving the Menu Bar to the left-right option and 
increasing or decreasing its value, will cause the picture to move
slowly across the screen (between 0  and  31 on the control).
The control for the vertical movement is operated in a similar way. 
However, beacuse the vertical position control has such a wide range 
of values (0-127), when the up or down key is kept pressed, the number 
will at first change in steps of one and then in jumps of four for 
ease and speed of use.
4. Clearing, selecting, X option and the ESC key.
All control options may be reset to their default values by using the 
CLR or DEL keys on the keyboard (the FIRE button on the joystick will 
also perform this action).
Many options on the menus do not have values assigned to them, these 
options are associated with performing a function or moving to another 
menu. To use these other options, you can press any of COPY, SPACE, 
RETURN, ENTER or FIRE.
The 'X' option is present in all menus. Its function is to return you 
to the last menu or, in the case of the main menu, to BASIC. Upon 
selecting the X option from the main menu, the computer will check 
that you really want to exit the program. Answer by pressing 'Y' or 
FIRE for YES and 'N' or any joystick direction for NO. For 
convenience, the 'X' key on the keyboard (X for exit!) or the 'ESC may 
be used to exit.
When returning to BASIC using the 'X' option, information such as 
inks, mode etc. is restored to the state set before entering the VIDI 
program. IThis   only   applies   to   the   ROM   ver sion. )
5. The GRAB menu, X on this menu nill return you to the MAIN menu.
Once you have decided that you are happy with the digitised picture, 
select GRAB and a new menu will appear. Notice that the picture has 
been 'frozen' - you have now selected that picture and can now do 
something with it.
SAVE is used to save the picture to disc or tape.
DUMP will print out a  copy  of  the  picture to an Epson compatible 
     printer using print routines unique to VIDI.
FILE PRINT and controL are documented later.
SWAP will allow you to swap between the picture you selected and the 
     previous frame - just in case  you  just missed it!.
6. The FILE menu, X   will exit   to   the   CRAB   menu.
SAVE does the same  as  the  save  option  in  the  GRAB menu, it 
     is repeated here for convenience.
Filenames must be entered when saving, loading or deleting. When these 
options are selected, a prompt and a suggested name will appear. Using 
left and right keys, you can position the cursor in the filename and 
alter it as required.
The method of inputting is very similar to the BASIC line editor. Left 
and right move the cursor (note that the cursor can also move over the 
X option, returning you to the GRAB menu) and CONTROL-left and 
CONTROL-right move to the start and end of the filename. DEL may be 
used to erase characters in the normal way and RETURN, ENTER or FIRE 
can be used to indicate that you are happy with the filename. A '?' 
may be used as a wildcard within the filename when DELETE is used.
When editing disc filenames, you can also edit the file extension by 
typing a dot. This will clear upto the existing extension and allow 
you to type in a new one.
LOAD option allows you to load a file to the screen.
     If ART option is active a PALette file will also be loaded.
DELETE allows you to delete unwanted files.
CAT  will display a catalogue  of  the  disc or tape.
  WARNING: using CAT will wipe out the other picture which can be 
  obtained by using SWAP. In 1 screen mode (see ConTRoL menu) the 
  picture will be lost entirely and cannot be regained. You have been 
  warned...
BIN  is used to change the type of file used.
  BIN is the normal screen only format (disc users are permitted to 
  alter the file extension). The other option ART saves two seperate 
  files. One is the palette file (with the extension '.PAL') 
  containing the screen mode and colours, folowed by the screen file 
  (with the extension '.SCR') which is the normal screen file. This 
  option is very useful for use in conjunction with 'The Art Studio' 
  from Rainbird as the palette and screen files are fully compatible, 
  (note: ART   is   invalid   in   Mode  0)
DRV  The final entry on the FILE menu is the storage medium.
  On a cassette only machine it will be permanently fixed at TAPE but 
  on a &&4/612B, it will default to DRV-A and can be changed to use 
  Drive B or Tape.
7. The PRINT menu, X   returns   to   the   GRAB   menu.
DUMP is the same as dump on the GRAB menu.
   Whilst printing, you may press CLR w DEL to terminate the printing. 
   ESC may be used in emergencies, but due to the way that grapnic 
   printing works, could lock the printer ON LINE and you may need to 
   turn it off and on again to reset it.
HORZ allows you to suloct the print direction.
   H0RZ will print the screen across the paper, with enough room to 
   print two screens on one sheet.
VERT prints the picture sideways on the paper producing a larger image 
     taking up a whole sheet.
1-STRIKE refers to single  print  density  while 2-STRIKE will print 
  using double density.
   A double density dump will produce a bolder image, but take 
   approximately twice as long to print.
CR+LF Will select between CR ONLY and CR ? LF.
  If it is found that there is a gap between every line printed, the 
  last option on this menu should be changed to CR ONLY instead of 
  CR+LF, this is to allow for printers that print an automatic line 
  feed every time a carriage return is received.
8.   The ConTRoL Menu, X nill   return   you   to   the   GRAB   menu.
INK  option sets the  colour  assigned  to a particular ink.
    The first number is the ink number, the second is the colour 
    number. The up or down cursor will change the number that is 
    highlighted. The ink numbers cycle from 0 to 15 in Mode 0, 0 to 
    3 in Mode 1 and 0 to 1 in Mode-2 (different sets of colours are 
    held for each mode) at the end of each cycle there is also a 
    feature to change the border colour. If DEL or CLR is pressed 
    when the cursor is ov«r the colour, that colour will be reset 
    to its default value. If the same is done over the ink number 
    then all the colours for that mode are reset. Note that in Mode 1 
    inks are in the order O, 1, 3, 2 with respect to brightness levels 
    due to the hardware design.
2-SCR allows you to change the screen update method.
    In 2-SCR mode, VIDI uses a technique of grabbing the picture to 
    memory before displaying it. The 1-SCR option will change this to 
    make use of only a single screen giving a 'rippling* effect when 
    grabbing a moving picture, but using less memory.
MODE allows you to alternate between different screen resolutions.
    The screen mode may be changed to accommodate Mode 2 (not to be 
    confused with the 2-SCR option!.). This mode has a higher 
    resolution but only two colours. When changing the screen mode, a 
    picture may be displayed in the wrong mode (which can give 
    strange effects). When you return to the MAIN menu, pictures will 
    be grabbed correctly in the mode that you have set.
    In Mode 0 the screen uill be updated in Node 1 until the picture 
    is grabbed, when it uill change to Hode 0. tlode 0 is synthesised
    by integrating 16 successive frames. This necessitates a still 
    video   source   (usually   a   video   earner a).
VW  removes the Menu line and view the entire screen.
    This is in case the bottom of the picture is incorrect. When 
    changing the vertical positioning, the end of the grabbed frame
    may be visible as a black bar. When VW is selected, the menu will 
    vanish until you press any key, when it will return.
NOTE: Pressing   "V"   on   the  MAIN menu  Hill   produce   the 
      same  result.
RESET returns all parameters to  their original values. - except 
      the 1 or 2 screen flip mode.
We have now covered all of the functions contained in the interactive 
VIDI software. If you have had difficulty in understanding any of the 
functions, read over the appropriate section again and experiment with 
the software itself.

THE RSX COMMANDS

As was previously mentioned, the software supplied can also operate 
using RSX 'bar' commands from BASIC. However, to write programs 
incorporating VIDI, you will need to have some knowledge of the BASIC 
programming language of the CPC computers. If you are unsure on 
programming techniques, see the example programs on the System disc 
supplied and consult your Amstrad User Guides.
All the other external commands can be called directly or from a BASIC 
program. Most of the commands have parameters after them separated by 
commas, although default parameters are assumed if they are missing.
When using BASIC 1.0 on the  464,  it is necessary to pass string 
variables to these routines by using a command such as:
A$="FRED":|VIEW,@A$
whilst, if using BASIC 1.1, you may just type;
|VIEW,"FRED"
Commands are listed with their names and entry conditions. Default 
parameters are also listed. So, missing out a parameter in brackets 
will use that default value.
Parameters called 'scr* refer to the screens at &4000 or &C000. A 
parameter of 0 represents the screen at &C000 and 1 uses the screen at 
&4000. If a 6128 is used, or an add-on 64k RamPack then frames can be 
grabbed or moved to the banked ram, with these blocks being addressed 
as screens 2-5. The default for this value is always ttie current 
screen. The commands are as follows s–
|VBANK,scr    For 12Bk CPC's. It allows selection of banks 2-5
              into the memory location of bank 1 <8.
              All commands (e.g. VGRAB) which write to the current
              screen will update the selected Bank if VS,EE is set 
              to scr 1. N.B. The CPC hardware will continue to display 
              the original screen (1) if it is selected as the viewing
              screen for example by VSEE,1. However the Firmware will 
              write to the new Bank. The viewed screen, therefore, 
              remains unchanged.
|VBORDER,n    Sets the Border colour to n (0 - 26).
|VIDI(,s)     Enter  the  interactive   program.   Parameter  S
************  should be 1 or  2  to  set  1-SCR or 2-SCR modes.
* RON ONLY *  Unless using ROM, this  command  is seperate from
************  all the others due to space limitations.
|VBRI(,n)     Sets the brightness to n.  Default=7.
|VCLEAR(,l,r,t,b)(,scr> 
              Clears window (left,right,top,bottom) on specified
              screen to current |VPAPER ink. Default is current
              |VWINDOW coordinates and current screen. If only one 
              parameter is present it is assumed to be 'scr'. See 
              section on WINDOWS for details  of  specifying 
              coordinates.
|VC0N(,n)     Sets the contrast to n.  Default=7
|VCONVERT(,scr) 
              Swaps inks 2 and 3 on screen (works in mode 1 only). 
              This is useful when dealing with other printer or 
              graphics routines that need the ink brightness to be in 
              the order 0,1,2,3 instead of 0,1,3,2 (the built-in print 
              routine will cope with either).
|VCOPY (,sscr (,dscr)) 
              Copies a screen from source scr, to destination scr. 
              If only one parameter is present it is assumed to be the 
              source with the current screen as destination.
|VDUMP(,p)    Dumps current screen to EPSON compatible printer 
              using 27 possible shades for displayed colours. The 
              parameter is bit significant:
                  Bit=0 (off)            |    Bit=1 (on)
                 ------------------------+------------------------ 
                  Bit 0 = CR + LF        | CR ONLY         (add 1)
                  Bit 1 = Normal Density | Double Density  (add 2)
                  Bit 2 = Horizontal     | Vertical        (add 4)
              If you are unsure of Binary arithmetic, to select the 
              functions you want on the right of the table just add 
              together the number listed by them.
              e.g. |VDUMP,6  would  print  a  vertical  double density 
              screen giving  carriage  returns and line feeds. 
              Default=last setting.
|VGET(,scr>   Grab a  frame  to  a  screen  without  doing  any
              setting up. VGET is slightly faster that VGRAD.
|VGRAB( ,scr)  Grabs a -frame to a screen, setting up colours,
               made, screen offset (in case screen has been scrolled) 
               etc. Note that values for colour and mode are held 
               seperate from the normal BASIC values. (See |VMODE 
               |VINK  etc.)
|VIEW,filename Takes a string parameter and loads and displays a 
               palette and screen file. Compatible with Rainbird's
               'Art  Studio'. Only specify the name part when using 
               disc – not drive, user or extension.
|VINK(,i(,c))  Sets ink 'i' to colour 'c'for current VMODE. If 'c' 
               is missed out, colour will default to its normal 
               setting and if no parameters are specified, all inks 
               for that mode will be reset.
|VMODE(,m)     Sets current grab mode to mode 'm'. Default=1.
|VPAGE(,m(,scr)) 
               Converts screen into a form suitable for AMX 
               PageMaker program. PageMaker has the -facility for 
               loading in Mode 0 or Mode 1 screens and converting 
               them to its normal Mode 2. However, the inks must be 
               in a specific order of brightness, SVPAGE will perform 
               this conversion for normal VIDI screens. The screen 
               should be saved after |VPAGE by using the BASIC save 
               command   -e.g. 
                            10   LOAD "VIDISCR4.BIN",&C000
                            20   |VPAGE,1,0   ;REM   mode   1,screen 0
                            30   SAVE "PAGESCR4",b,&C000,&4000 
               Default – current mode  and  screen.  If only one 
               parameter is present it is assumed to be 'scr'
|VPAPER(,i)     Sets background paper ink for |VCLEAR.  Default=0.
|VREAD(,x,y)    Reads data from currently defined scan window 
               (see SVSCAN) and displays it at screen position x,y. 
               (see the WINDOWS section further on for details of the 
               x,y coordinate system). The whole scan window is forced 
               to lie within the screen boundary. Default=original 
               scan window position. If VMODE=0 then no action is
               taken.
|VRESET        Resets all RSX parameters to their default values.
|VSCAN         Scans a frame into  VIDI  ram, without displaying it, 
               used in conjunction with iVREAD for grabbing and 
               displaying windows (see the |VWINDOWS section).
|VSEE,scr      Reset  screen  offset  (if   scrolled)  and  view 
               screen 0 or 1. Useful for flipping between screens 
               after grabbing.
                   NOTE: If screen 1 (&4000) is used care must be
                   taken not to overnrite any program or data that
                   is residing there – possibly causing the computer
                   to 'crash'. This can be avoided by setting HIMEM
                   to  &3FFF (MEMORY &3FFF) before   using   the
                   RSX's.
|VSET          Set up VIDI values  in  preparation for grabbing.
               Note: |VSETKVGET is equivalent to '.VGRAB.
|VSMALL,x,y    This command has the same restrictions as |VREAD, see 
               manual.  It  will  scan  a  complete  screen, compress 
               it down to quarter size then display it on the current 
               screen, at position x,y.
|VSPRITE,l,r,t,b,x,y(,sscr(,dscr)) 
               Copy a window from one area of the screen to another. 
               Parameters are left, right, top, bottom of the source 
               window and x, y of the top left corner of the
               destination - all in VIDI coordinates (1,1 to 80,200) 
               all must be present. If both screen parameters are 
               omitted the current screen is used, if one screen 
               parameter is present then it assumed to be the source, 
               with the current screen as the destination.
|VWIND0W(,l,r,t,b) Sets a scan window for  iVREAD to use. Parameters
               are - left,  right,  top,  bottom. The coordinate
               system used is 1 to 80  for 'x' (columns) left to right 
               and 1 to 200 for 'y' (rows) top to bottom. 0 means the 
               relevant edge of the screen, i.e.Parameters of 0,0,0,0 
               means the whole screen.
               The window defined has a maximum full screen of 80 
               columns and 200 lines, where top left = 1,1. bottom 
               right = 80,200. When a window is defined, VIDI uses it 
               for the IVREAD and SVCLEAR commands. Default=whole 
               screen.
|VXP0S(,n)     Sets horizontal frame position. 0-31. Default=16.
|VYP0S(,n)     Sets vertical frame position. 0-127. Default=48.

TROUBLE SHOOTING

Video signals from different manufacturers equipment vary considerably 
and since it is impossible for us at Rombo Productions to test out
every conceivable video source, some fine tuning may be required to 
obtain optimum results.
If VIDI is not displaying a picture at all then first check that the 
unit has been installed correctly. Check all connections, particularly 
the VIDEO OUT on the video. This is almost always directly beside the 
VIDEO IN with an identical socket, make sure you have connected the 
right one.
If your camera/video does not have a BNC type of socket, check that the 
VIDEO OUT signal is actually composite video and not RGB or modulated 
RF. It ic possible to convert RGD into composite video via a patch lead 
- check with your video supplier, however, RF (or TV) modulated signals
are not suitable for VIDI. Some videos are fitted with phono sockets for
VIDEO OUT and in this case you will require a phono/phono cable – available 
from hi-fi or video shops. A few videos and televisions are fitted with
a SCART interface (Peritel in France). Suitable composite video is
available from this interface via the correct lead - consult your 
video dealer.
VIDI will only grab a frame  after  the detection of a vertical sync 
.pulse within a certain amount of  time.  Some videos produce erratic 
sync pulses on  pause  and  fast  search  and  VIDI  may not respond 
correctly in this mode.
The aspect ratio of the grabbed picture is controlled by a small blue 
adjustable resistor situated near to the edge connector lying flat on 
the VIDI board. This is calibrated before depatch, and as this setting
interacts with the software controlled horizontal position it should 
only be adjusted with care. This adjustable resistor also controls the
detection of sync signals to a small degree, if your screen looks like 
a chessboard when first switched on (with the video attached) turn this
control clockwise until the screen displays the video picture.
All video pictures produce signals of varying strengths. The digital
contrast and brightness controls are initially set by on board variable
resistors. These are the blue square components situated and labelled 
next to the VIDEO IN connector. The CONTR. and BRIGHT controls are
calibrated by ROMBO, so before adjusting, the original setting should 
be noted. The CONTRAST control is unlikely to be of any use but the 
BRIGHTNESS control is useful to give fine adjustments for the software
settings. This is especially so when using Mode 0, as the software 
contrast and brightness settings are ignored. Use the external BRIGHTNESS
control to set the overall brightness of Mode 0.

TECHNICAL DETAILS

The Amstrad Computer screen has a maximum resolution of 610 horizontal 
pixels by 200 vertical lines. An average TV picture has a definition
greater than this, so compromises have to be made somewhere!.
To maintain a correct aspect ratio on the computer screen, the VIDI
frame store is 'windowed'over the TV picture and grabs some 757. of 
this picture. However if required clever use of the RSX commands can
enable whole frames to be stored and 'edited'together.
The software Contrast and Brightness controls do not actually modify
the video signal, instead they alter the digital sampling width (contrast)
and level (brightness). Practice may be required to understand their 
actual effect on the sampled picture.
The VIDI hardware stores the grabbed frame into its own internal memory,
from where it can be moved to the computers screen or other memory.
In 2-SCR mode, two screens are filled and displayed alternately. These
are located at addresses &C000 (the normal screen) and &4000, each 
occupying &4000 bytes(l6K). When using this mode, it is advisable to
set HIMEM in BASIC to be »or less to avoid program or
variables being overwritten.
1-SCR mode will always use the standard screen at &C000 and HIMEM
need not be altered. To enter the program in a specific SCR mode,
use |VIDI,l or |VIDI,2.
We are pleased to help with any technical queries relating to VIDI
and receive suggestions for future enhancements.
Software upgrades and developed applications will be made available
from time to time for a nominal charge (media cost + PI.P). If you
have any routines or programs you would like us to include please 
send them to the above address (copyright will be public domain).
Thank you.

PAGE MAKER OVERLAY

There is a file included on  the VIDI disc called PAGEMAKE. OVT. This
is an overlay file allowing VIDI to  be used within the AMX PageMaker
program.  The PA6EMAKE.OVT file  should  be  copied onto your working
copy of the Pagemaker  disc  by  running  PAGEMAKE.BAS.   The VIDI is
accessed via the 'SCANNER' option within Pagemaker.
AMX PageMaker works in mode 2. The SCANNER option allows VIDI to grab
pictures direct to the screen in mode 2. When you select 'SCANNER' 
you will notice a status line appear underneath the command -
            Brightness  8 Vertical 64 Horizontal  22
The brightness refers to the iVBRI parameter in VIDI. It can be 
increased by pressing the EXECUTE button. When it goes past IS it 
will wrap around to 0.
The keyboard cursor keys are used to control the Vertical 
and Horizontal settings. The frame can be positioned so that 
any part of the picture is available to any part of the screen 
window.
The MOVE button will freeze the current frame whilst pressed.
The CANCEL button will capture the current frame and return to the
PageMaker options.
If a GRAPHICS WINDOW is currently defined within PageMaker then VIDI 
will only grab into the part of the screen lying inside the graphics window.
This feature, for example, allows powerful dynamic displays to be 
generated with text and moving pictures on the screen at once!
Pictures requiring better shading than mode 2 should be grabbed and 
saved outside of PageMaker using the normal VIDI commands in mode 0 or 
1. We have achieved best results with mode 1. After conversion with 
the |VPAGE command these can be loaded into PageMaker via the 
FILE - SCREENS option. Remember the top of the screen is lost 
when loading into PageMaker so frame your picture accordingly.

The  BASIC  Programs.

Several BASIC programs are included on the VIDI disc as examples 
of using the VIDI RSX tfommands.
Me recommend that you load and list these programs to see just 
how simple it is to produce apparently complex digitised 
displays.
The BASIC programs all have a filetype of *.BAS*.
The start of each program listing contains notes on the use 
and function of the RSX commands within the program.

QUE DIT LA LOI FRANÇAISE:

L'alinéa 8 de l'article L122-5 du Code de la propriété intellectuelle explique que « Lorsque l'œuvre a été divulguée, l'auteur ne peut interdire la reproduction d'une œuvre et sa représentation effectuées à des fins de conservation ou destinées à préserver les conditions de sa consultation à des fins de recherche ou détudes privées par des particuliers, dans les locaux de l'établissement et sur des terminaux dédiés par des bibliothèques accessibles au public, par des musées ou par des services d'archives, sous réserve que ceux-ci ne recherchent aucun avantage économique ou commercial ». Pas de problème donc pour nous!

L'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent  du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko.
