You can use a 32 bit version or a 64 bit version. A 64 bit version is recommended.
A decent size disc with ample space is recommended. At least 500Mb of free space is recommended.
A Solid State Drive (SSD) is recommended for faster start-up.
The faster the better. We suggest an I7.
The more the better. On a 32 bit version O/S you are limited to 3GB usable (the extra 1GB is reserved for your video card). I recommend at least 2GB on Windows XP and 3GB on Windows 7 and later. Windows Vista is not recommended.
You must have at least a 24 bit color video card. All modern video cards support 24/32 bit color.
Here the bigger, the better. The Monitor is your view into your design. I recommend at least 1920 pixels horizontal.
AutoTRAX will work with multiple monitors and you can drag parts of AutoTRAX onto different monitors. AutoTRAX remembers the position of all its windows are restored them the next time you run AutoTRAX.
All modern video cards support at least two monitor outputs, and many support even more.
You definitely a 3 button mouse with a central thumb wheel. The thumb wheel is use you zoom in and out and pressing down the thumbwheel/middle mouse button pans the view.
