 *   DT3003-PGL, DT3004, DT3005, DT3004-200
 * Author: ds
 * Updated: Mon, 14 Apr 2008 15:41:24 +0100
 * Status: works
 *
 * Configuration Options: not applicable, uses PCI auto config
 *
 * There is code to support AI commands, but it may not work.
 *
 * AO commands are not supported.

/*
 * The DT3000 series is Data Translation's attempt to make a PCI
 * data acquisition board.  The design of this series is very nice,
 * since each board has an on-board DSP (Texas Instruments TMS320C52).
 * However, a few details are a little annoying.  The boards lack
 * bus-mastering DMA, which eliminates them from serious work.
 * They also are not capable of autocalibration, which is a common
 * feature in modern hardware.  The default firmware is pretty bad,
 * making it nearly impossible to write an RT compatible driver.
 * It would make an interesting project to write a decent firmware
 * for these boards.
 *
 * Data Translation originally wanted an NDA for the documentation
 * for the 3k series.  However, if you ask nicely, they might send
 * you the docs without one, also.
