I suggested that back in an earlier thread, but the "MCT" logo on the 
board differs in appearance from the logo used on the PC stuff.  If 
anyone has a 1982 or so JDR catalog, that might confirm the suspicion 
one way or another, but I'm pretty sure after some investigation that 
this isn't a JDR MCT product.
