For the sake of comparison with what the factory-original module compliment
says, I will note in quotes ("") what's on the CPU cover label:
1. "Not used"
This is where the IDC (Integrated Disk Controller) goes, IIRC. It's the
R80/RL02 controller board.
2. "M8389 FPA (Option)" (must be a
floating pt. adaptor)
Bingo.
3. "Not used"
Don't recall.
4. "M8390 DAP"
Data Path Module
5. "Not used"
Don't know.
6. "M8391-YA or M8391 MCT"
Memory Controller.
7. "M8394 WCS"
Writable Control Store - here is where the data from the tu58 ends up.
8. "MS730-CA"
9. "MS730-CA"
1Mb ECC RAM (each)
10. "G7273/Memory"
11. "G7273/Not for Unibus Option"
12. "G7273/Not for Unibus Option"
More RAM slots. "Not for Unibus" means it's a MUD slot (Modified Unibus
Device). You can't plug a termninator or Unibus cable into them, and only
some peripherals work here. At my former company, our COMBOARD I did not
work in a MUD slot, but the COMBOARD II did (we used alternate pins to get
the correct UNIBUS signals to the board).
13. "G7273/Unibus Option"
May or may not be a MUD slot. I forget.
14. "M9202" (and) "G7273/Unibus
Option"
What ever you do, don't install the M9202 terminator in a higher slot than
this. You need those G7273 Grant Cards in all the empty slots.

P.S. - I *may* have a set of 11/730 prints in storage. I'm moving soon.
I'll know in a bit. If I do, the biggest problem with copying them is
access to an 11"x17" copier. I won't sell my only copy - I've got an
11/730 in storage, the same one I've mentioned before.
