Versalogic VX-09T 9-Slot STD Bus Industrial SBC PC Card Cage WECO 2350 Zilog Z80

Versalogic VX-09T 9-Slot STD Bus Card Cage with Zilog Z80 Processor Card and Assorted I/O Cards. Used, removed from a WECO 2350R test system. 

Processor card contains a Zilog Z80 CPU, P/N Z84C0008PEG, Z80 DART P/N Z0847006PSC. 

Additional cards appear to be for serial ports and digital I/O, but I have no specs.
