I just bought a surplus Hewlitt Packard 2627A
graphics terminal without a communications
cable and I would like someone to please tell
me how it should be wired, i.e. what signals
are on what pins. The port 1 connector has 50 (?)
pins like those on multiline telephones.
Also any additional information on how best to
use this type of terminal for graphics would
be appreciated. I also need manuals for it.
Many thanks in advance.

Although the HP 2627A is no longer in production (but is available as a
remarketed product), the manuals are still in print, and are:
02627-90001 Users Manual $ 38.00
02627-90002 Reference Manual 25.00
02627-90003 Service Manual 17.00
5957-9918 Cabling Manual 17.00
I was surprised at the relatively high price of the "Users" manual until
I checked our library copy. It is printed in color, which is costly.
The datacomm pinouts are as follows. This also describes the HP 13222N U.S.
modem cable, if you substitute a 25-pin male DB25P connector for "Port 2".
Only those lines marked with an asterisk (*) are generally needed for use
with port selectors or retail modems.
