Howdy!
I recently acquired a DEC MicroVAX 4000-300 and I want to connect it up
to an old PC that I can use as a dumb terminal. Unfortunately, I lack a
proper null modem cable, but I have a nice length of phone cable (it's
the same connector pretty much, if you sand down the clip, right?) and
a nice length of serial cable with connectors on each end. My question
is, is it possible to jury rig these two pieces of cable, so that I can
have my VAX up and running for at least a single user (Ethernet will
come later! ;) ). If so, what lines should I cross (pin numbers would
be nice :).
Thanks.
Phil.

Interesting idea.
I just went through this, though fortunately found an MMJ cable in my
junkbox, with some MMJ hoods for making adapters.

This might be the adapter you are looking for, if you care to ebay for it:

If you decide to make your own, there is detailed information about the
pin-out on the www.tru64.org website in the FAQ:
http://www.tru64.org/pages.php?page=Tru64-FAQ-Hardware
I believe this is also in other DEC hardware FAQs and a VMS FAQ somewhere.
Note that depending on your terminal emulator, you may need to loop
RTS to CTS, and do not make the mistake I did of disregarding a
ground on both of the "RX-" and "TX-" leads.
