Description
Description
The ec500 system (thus far) comprises three main components:
* The primary board, 'error.core,' which has 9 oscillators & 3 mix busses
* The external i/o expander, which adds a microphone, 2 line inputs, and several auxiliary features
* The VGA adapter, which is necessary to interface the system with a monitor
