Ritchie Ms-100 serial connection

[Farr horizons]

Hi looking for help with connecting my Ms-100 to a computer and or multiplex to use the data in nav programs. The link ( www.Ritchie navigation.com/docs/ms-100) in a 2003 post gives doc not found message. I’m looking for wiring, NMEA sentence output and any other. The Ms-100 was working when removed from a Ockham system recently.
Appreciate any help.
