What do I need to work with ES32?

I'm glad you ask. You don't need that much, but some things are necessary.

Of course, you need a PC. It must be running a Microsoft OS. Anything since Windows 95 should do. But ES32 is only tested on Windows 98, 98 SE, ME, and 2000. I don't see any reason for it not to work on XP, but I can't guarantee anything. The hardware shouldn't matter much. Of course it will run faster on faster hardware and the more memory your system has, the better. Since ES32 is designed to let you visually explore your data, you should have a screen resolution of at least 1024 × 768.

Next stop: the data. Obviously you need data because ES32 feeds on data.
