Great! thank you Glen and also Michael T. for the identifications.
So this appears to be a PDP-11/23 with this FC-202 floppy controller.
1. I have read that the card and the drives were compatible with the dec rx02
drives. Why would the CRDS even bother to redesign a card where DEC had
perfectly good working ones? Anyone know if there is any value in keeping the
FC-202 or just keep with the DEC cards?
2. Any idea on that other card?

I could not find any designation on the backplane. It is a
wire-wrappable backplane. I don't know if it is Qbus, unibus or
whether it is 18 or 22 bit addressing (this is because I am a newbie in this
area).
