 I have one - for a MicroVAX 2000.  I rarely used it.

 We had one in the 1980s.  You are right.  It didn't. 
I wonder if that was a VAX-specific issue.  It streamed fine on J-11 based PDP11 systems
running RSTS.  While most VAXen have faster CPUs than PDP-11s, that doesn't
necessarily carry over to I/O.
