UC04 configuration

Yes :-) In fact it does (I think). My problem is that I haven't documentation for this board. The docs related with the UC07-08 appears to be useful, but there is a point where I can't advance. The practical object of study is the installation of Unix 2.11BSD into my PDP-11/23 PLUS. The lights in the board tells me that the disk is being accessed by the Unix Installation Program. But, when I tells Unix to install over ra(0,0,0) device, it takes a little time while the lights in the board bright during a few seconds, an finally... nothing: no lights, etc. The device appears that could be addressable and works in the PDP machine, right, but I'm stopped. I believe it could be neeeded to access some kind of formatting program in the rom of the board. I saw how to do it with one UC07-08 in one Vax environment, but I'll very happy if anybody knows how to manage the UC04 in this way. Thanks and Best Regards Sergio
