IBM 3174 C 6.4 Microcode Disks?

Classic Computer Fans,
I posted this to the IBM-Legacy-Hercules mailing list. I just realized it
probably wouldn't hurt to post it here too.
I'm finally in possession of a box that hopefully is capable or can be made
capable of connecting a real terminal to Hercules. It's a 3174 11L. It was
retired last year where I work. I finally got the okay to save it from
being sent to a scrapper. I love the build quality of older IBM gear,
except when I'm trying to move such gear. Between the 3174 and a 9406-520 I
also acquired, I pulled or strained something in my left arm moving them
into place.
It's currently wired to run on 220v. I think I've seen mentioned somewhere
that it can be changed to run on 110v. If that's the case, does anyone have
a pointer to documentation on what's involved?
It has dual floppy drives. At least one drive is a 2.4MB drive. But, all
the microcode disks I have are at level B 4.6. Does anyone know where I can
get a set of C 6.4 control and control extension disks. From what I've
heard those are what's needed to enable an attached terminal to connect to
other systems via telnet.
It has a token ring card. I will probably be able to get the MAU it was
connected to, and possibly the router that acted as a token ring to Ethernet
bridge.
I'm not sure how much memory it has. Does anyone have any tips on
determining the amount of memory it has, and/or identifying its boards?
These are the numbers on its boards:
9210
9351
9052 z2
9053
9501
Plus the boards for coax connections.
