uVAX II Memory Board

I have an interesting question. Can this board be used as additional ram in a PDP-11? If so, how might it be done? I have a Qbus Memory board that must be from a uVAX II - M7609-AP with 288 (I hope I counted correctly) memory chips 4256L-15 8726255 A 21-22422-42 R with the standard male 50 pin header at the top to be connected to a uVAX CPU. If my arithmetic is normal, does this make it an 8 MByte memory? Now, I am no hardware expect, in fact about all I can do with a soldering iron is to plug it in and unplug it - before it gets too hot and I burn something. But, is there any way that a regular PDP-11/73 could see this memory and use it in some manner? Otherwise... I don't expect that anyone will want it, but if so, can I swap it for a regular PDP-11 Qbus memory of 4 MBytes? Sincerely yours, Jerome Fine
