Epic is a system that converts a PC into a physiological work station. It consists of a board in the computer with its own processor and memory, that is used for fast high-resolution data acquisition and stimulus generation, connected to an expandable user interface with high-quality input and output modules specially designed for the requirements posed by physiological stimulation and recording. There are no knobs or switches: everything from sampling speed to the input conditioning filters is controlled through the computer. The software, which is written in Forth, runs in parallel on the board and on the computer itself and provides a configurable front end that can be set up with an initialisation file to be as complicated or as simple as the user wants, together with tailor-made help files and sets of inital parameters. For this reason, and because the interface has been designed by a physiologist rather than by a computer person, students find it particularly easy to use, and it is in fact installed in many teaching and research laboratories all over the world.
There are two versions of Epic. The Classic version has an external unit, the Epibox, that houses the input and output modules and provides connections to the experimental preparation. Epic Compact compresses the Epibox, implemented with two out of the possible four high-impedance inputs, into a unit that fits into a standard disc-drive slot.
