[vcf-midatlantic] MMJ cables for cheap

 I think several folks have the crimp tools and jacks/plugs needed to make MMJ leads. The problem I have had is finding 9 or 25-pin adaptors when I want to plug into a non-DEC terminal.  The last cables I made were "bodged" from a similar cable. I cut one RJ12 off and replaced it with an MMJ plug, so I ended up with an MMJ<->RJ12 lead. I then tweaked an RJ12 DE-9 Socket to connect to a laptop with serial port. In fact these leads are a cheap source 6-Way cable...
