Just for reference these are AlphaServer boards. The first board is either an E2067-DA or a 2063-DB CPU Module Board
The second board I have never seen.. looks like a later model VAX CPU module board possibly
The 3rd board is a Memory Module Board in the MS7CC series. Sadly someone pilfered the RAM out if it before Mike came into possession of it-- Just imagine that all those empty slots at the top of the board are chocked full of RAM! This is the same series board I had won on auction from a guy on Ebay and he never shipped it.. GRRRR.. eludes me again!
