the first card has two mmj ports one coax port and one 15-pin AUI port. Has the inscription DIGITAL 25793 50-21879-01. This is obviously a network card module or something. I am more concerned with what DEC/DIGITAL computer this is used for. It has a vme/nubus kind of connector that plugs it into the motherboard of the DEC

The second is a strange little card , that is obviously SUN Microsystems made. It has a SCSI port and a port that looks like a phone or 10BASET port with the inscription "TP" and a left/right arrow. This also has the following ID marks (5012981063784 -01 REV 50 LSI)
