This is an alternative multiuser motherboard for the QBUS-based MicroVAX 3300/3400; it contains the CPU (a CVAX chip), 4 Mbyte of main memory, a DSSI secondary storage device controller, and an Ethernet network interface.
It differs from other MicroVAX 3300/3400 motherboards by the main memory ICs used, in this case ICs from Hitachi.
There were other versions, too, e.g. the "-AF" version, which used main memory ICs from Toshiba.
