There's quite a bit of info buried in the forum, so do a search or browse the hardware section.

That's a standard LCD so you can connect it to a parallel port by following the wiring on the Smartie site: http://lcdsmartie.sourceforge.net/circuits.htm Use the first (top) diagram for your LCD. All you need is some cable (you can cut up an old printer cable) and a 5V power source (eg spare disk drive connector).

You should be able to set your Smartie display driver to HD44780 and the port to LPT1. Some PCs seem to have problems communicating with the LCD on a parallel port. You can try the different port setting in your BIOS (ECP/EPP/SPP) if you have problems.

To connect that LCD via USB, you need an interface module (and associated driver) like the one described in this forum thread: http://forums.lcdsmartie.org/viewtopic.php?f=11&t=1540
