Probably you had good reasons for not entering any of my change requests
into the final form.

Nevertheless I would like to insist at least on the correction concerning
the interface of the PS :
------------------------------------------------------------------------

> 	12 bit -			$1500

>>>  ** NO ** !   <<<  That would be too bad!
        ==
All ADA variants are 16 bit D/A and A/D, have 8 bit dig. I/O, fully
isolated analog stage, low thermal drift components. Price differences
reflect differences in stability against thermal drift:

	0.5 ppm/deg C Drift             $1900
	1.5 ppm/deg C Drift             $1500
	5.0 ppm/deg C Drift             $1300
------------------------------------------------------------------------
The notes in its present form would mean that we at BESSY are as stupid as
to spend $1500 for a 12 bit IO card ...

Roland.
