Here is another cable/connector question.  On the DECStation, to 
boot "headless", it appears that the serial port to use is the 
one on the far right, when the unit is right side up. ;)

Looking at the NetBSD/Pmax web pages, I see that this is described
as a MMJ-6 connector.  Where is the best place to purchase such 
a serial cable?  

Reading through the archive of this mailing list is interesting,
and provides valuable insights.  For example, several years back
there was a thread on booting these 3100s headless, with the 
exclamation that it had truly made it to "FAQ status".  Well ... ?
Anyway, in those messages, a pointer was given to the Ultrix FAQ,
which is fairly easy to locate on the net, and in the hardware section
they talk about how to make a mouse loopback connector.  Someone, 
( I think Simon ) suggested using a paper clip.  Will this really 
work, or is there something better I should try to get ahold of?

Thanks in advance for any insights.
