That was the VAXstation-11/RC.  Marketing wanted a VAXstation with
fewer backplane slots that it could sell at a cheaper price.  Rather
than manufacture a different board, they just filled the extra
backplane slots with glue to render them unusable.  "RC" officially
stood for "restricted configuration", but we in Engineering called it
"resin caulked".
