System Requirements - Mac OS
To use BackJack, your system must meet the following minimum requirements:
a. A Macintosh with at least a 68030 microprocessor (68030/40 recommended)
For best performance, we recommend that your Macintosh have at
least a 68030 microprocessor. If you have a Power Macintosh, BackJack
will be accelerated for Power Macintosh.
b. System Software Version 7.1 or higher
If you're unsure of the system software version installed on your
Macintosh, choose the first item from the Finder's Apple menu
(About This Computer, About This Macintosh or About This Finder),
depending upon the version of the system software you're using.
A window appears displaying the system software version number.
If your version number is below 7.1, you won't be able to install
BackJack. System software upgrades are available from most Macintosh
software distributors.
c. At least 7 megabytes (MB) of available hard disk space
The easiest way to check the amount of hard disk space available
on your Macintosh is to open any folder in the Finder. If you're
using Icon View or Small Icon View, the window header of the open
folder displays the amount of available hard disk space in the
right-hand corner. To install BackJack, you'll need at least 7
MB available.
d. At least 3 MB of available memory (RAM) to run BackJack, therefore
we recommend a minimum RAM of 8 MB.
To find the amount of RAM installed on your Macintosh, choose
About This Computer, About This Macintosh or About This Finder
from the Apple Menu (depending upon the version of the system
software you're using). Figures pertaining to RAM are in the window
that appears. The Total Memory field displays the amount of RAM
installed in your Macintosh which should be at least 8192K (or
8 MB). BackJack requires 3000K or 3 MB of this 8 MB in order to
run. Users with large numbers of files (more than a few thousand)
will need more.
e. PPP, SLIP or direct network access to the Internet (14.4 kbps
minimum)
28.8 kbps or better is definitely recommended
f. Open Transport v 1.1.1 or greater
To determine whether you are running Open Transport, select Control
Panels from your Apple Menu. If you have a TCP/IP Control Panel,
this means that you are running Open Transport - check to make
sure that the version is 1.1.1 or greater. If you simply have
a TCP Control Panel, you are not running Open Transport and can
obtain a free version by visiting www.apple.com.
