[GreenKeys] Using ASR 33 with PDP 11/05

[Christian Gauger-Cosgrove]

As a corollary which just crossed my mind - due to the fact I just
noticed the link to the wiring diagram of the cabel between the DL-11
and the ASR-33/ASR-35 - the extra two pins in the DEC cable seem to be
glorified ground connections (if I can make out the table correctly),
while all you need are the four "standard" lines of TxD+, TxD-; RxD+
and RxD-.

Also, sorry for the extremely short post.
