[pups] Memory Error 46 on a PDP 11/73

[Nutech]

Hello,
I am getting the following error when I try to boot my PDP. The Card
details for the CPU and the Memory Board are as under.

Here are the details of the Various cards.
Slot 1(ABCD)     KDJ11-BB (M8190)
Slot 2(ABCD)     MSV11-QA(M7551)
Slot 3 (AB)         M3107
Slot 3 (CD)         Blank
Slot 4 (AB)         Solna prinitng machine card
Slot 4 (CD)         BIT Scandiavia card
Slot 5 (AB)         Blank
Slot 5 (CD)        M7555

Can some one please guide what I can do besides replacing the old card
with a new card.
Regards,
Shroff
