(About CAM)
CAM is a French-Canadian Amiga public domain collection, put together by
Club Amiga Montreal. They cover most of the usual areas a normal public
domain library caters for, and have an extensive back catalogue of
utilities, applications, games, image disks and sound disks, most of the
material being ready-to-run. Some files can also be found in other
collections <such as the Fred Fish library>, however, CAM have concentrated
on themed disks - by doing this, they have organised their collection in a
more logical and easy-to-scan manner.
(Getting Started)
The CAM index needs the following files to operate:
Amigaguide and AmigaGuide.info in sys:Utilities/
reqtools.library, amigaguide.library and arp.library in libs:
LhA and CAMThing in c:
help.guide in s:
There is an Install utility available in English and French to
automatically set this up - look for 'Install CAM' in the 'Install' drawer.
It adds all the above files to your WorkBench system, checking for newer
versions of all files. You may wish to re-install ReqTools to add in your
own localisation - more details on this are in the drawers ReqTools and
AmigaGuide, but 'Install CAM' will be enough to get you started.
Copy your version of WhereTo to wherever you want, or simply run it
from either CD by clicking on it. This small utility allows you to
select an AmigaDOS path to unpack the CAM disks to - if you wish to
rebuild the original CAM collection, this will be a floppy drive such
as "df0:". If you are using CAM as a reference archive and only use
small parts of it, you may want to unpack to "ram disk:". WhereTo
uses the ReqTools file requester - press the right mouse button to
get a list of drives and volumes.
(Using the CAM CDs)
Then open up the CAM.guide icon to obtain a HyperText index of the disks.
To ease loading times and memory use, the collection has been split into
ranges of disks. After the title and contents of each disk is an 'Unpack'
button which decompresses the disk to wherever you have selected with
'WhereTo'. CAM releases are sometimes split over several disks - separate
buttons are available for each disk - eg 'Unpack disk B'. As well as the
displayed buttons, text search and markers are available through menu
options. More documentation about AmigaGuide can be found in the 'Install'
drawer.
You will need formatted blank disks to unpack to df0: or similar - the
program SuperDuper is included in the Extras drawer to do this. For file
management, DirWork is also found in Extras. CAM releases 1 to 649 can be
found on CD 1, 650 onwards on CD 2. The index will prompt you to change
CDs as needed.
(Technical notes)
Why AmigaGuide?
Due to the size of the CAM index, it was impractical to have the text files
in one block, for small machines. This is also the reason we have used LhA
as the compression system for the CD. DMS would be faster for unpacking to
floppy disk, but it requires a floppy drive and a lot of memory on small
systems - many users will own a hard drive or can unpack to the RAM disk.
The index was also too big to write a custom front-end and and reformat, so
AmigaGuide was used. This allows the index with full descriptions to be
used on all Amiga systems, with links to LhA.
Customising
If you want to specify the path automatically when you boot, set the
environmental variable "CAMOUT" in your startup-sequence, or copy it into
ENVARC: if you're using Kick2.1 and higher. This is what the program
'CAMThing' looks at when unpacking an archive.
CDTV/A570 and memory problems
If you're using a machine with 1 meg of RAM or less, you may run out of
memory when using the index and unpacking disks. A special boot-disk is
available if you do the following:
Make a copy of your Workbench disk and boot up from it with either CAM CD
in the CD-ROM drive. Open a Shell or CLI, and enter this:
cd0:cam.dex df0:
and press RETURN. Confirm any requests, and this will unpack the special
boot-disk, over-writing your copy of the Workbench disk with the boot-disk.
This is why you must use a COPY of the WorkBench disk. You can now boot
from this new disk with either CAM CD in the CD-ROM drive, and have full
use of the index.
