The Renix system is inherently unreliable, on not just Renaults but Volvos and Jeeps too. Off the top of my head, i don't know any other cars that use it.

Yes the 740 does use a EZK with a vac line for map signal. that is done as the head mounetd dizzy can not accommodate an advance mechanism so the advance is done by the EZK. Base time is set by rotating the distributor base plate moving the point the hall sensor is triggered.
Renix is all calculated by the renix module (also has a map signal)
The above two systems when giving trouble are often best replaced by the 240 system
LH is all done by the ECU's (mostly EZK but it is signaled by the jetronic ECU)
