Dectalk Express synthesizer question

[Alex Snow]

>From what I remember, some of the Dectalk Expresses use MMJ (a 
proprietary Dec connecter) for their serial port.  You need to find 
mmj->db9 cable...I'm looking for one of these at the moment for my 
VAXstation 3100, which uses the same type of connecter, and they seem 
a little hard to find.  You can grab an MMJ patch cable from Blackbox, 
and try and find a db-9 to mmj adapter on ebay or the like which is 
what I will probably end up doing.
