The system I used was the third large image down on this page:

Magnavox INS

The woman in the mini-skirt didn't come as standard! The Silent 700 (mis-named!) teletype was my basic workstation. The Satnav receiver is above the tape decks in the left hand rack. I knew Bob Horne very well, and he would often pass programme patches to me over Portishead Radio, to vessel callsign Hotel Oscar 5389:

"0110011, 11001110, 01100110, how copy" ....etc. Sometimes for half an hour, with me reading back each block for confirmation. It would piss off other vessels in the radio queue behind us, I can tell you.

Contrast with the instrument room on a more modern vessel:
