INSTALLING
To install Circa 7000, simply Unzip 7000.zip in the directory you want the
game. 

Circa 7000 runs in DOS and requires a 386 PC or better.  The faster the
computer, the better the performance will appear.  Your monitor must be
capable of VGA.

Circa 7000 uses around 600K of RAM depending on the size of the scenarios and
support files.  

To free up RAM, you can try setting up CONFIG.SYS to only include:
DEVICE=C:\DOS\HIMEM.SYS 
DEVICE=C:\DOS\EMM386.EXE 260 
DOS=HIGH,UMB

and your AUTOEXEC.BAT to only include:
rem PROMPT $p$g
