Board identification

Hi All, Just unloaded a 11/34 with some very unusual cards in the machine, but the most intresting thing is that it had a PC11/PR11, an RX01 an Rk05j. The cards I cannot identify are labelled as follows: DSS11XA DSS11B There was also a backplane with 3rd party quad cards, with white handles. They only have number, no texts. They are : HA.C174D0820 HA.C174D0804 HA.C174D0817 There are two Berg connectors on two of the cards. It also came with a VT30 interface. What can I do with it besides connecting it to a color monitor? Is there some usefull S/W for it available?
