'78 CB750 regulator/rectifier

I'm trying to get this bike sorted out and have discovered that the regulator/rectifier is MIA.
Dumbass question of the day...
Should I expect to see spark at the plugs with it missing?
If so, I still have other issues :

Next dumbass question...

The '78 CB750 has seperate regulator and rectifier?
Because it seems both are MIA :

'nother dumbass question...
I found that it does have a Dyna S electronic ignition. Could it be that it replaced the OEM regulator and rectifier?
And if not, is there a replacement that combines the reg/rec in one unit?

Nevermind, I think I have it figured out.

I fuckin HATE electrical problems.

Oh, and the answers to the questions are:
1) No
2) Yes
3) No
4) Yes
