Sigma floppy controller ?

I have a Sigma floppy disk controller which I believe to be for Qbus.
The assembly number is 400255 rev B and S/N is 4331. It is a dual board
and has a pair of 2901 bit slices and an assortment of bipolar PROMs.

 From the field guide, I found this entry:

SDC-RXV31 Q Sigma floppy disk controller. Emulates RXV21/RX02.
                             (Supports Mitsubishi M2696-63)

I assume this is the one.

Does anyone have a manual for this controller (copy or scan)?
