IBM 3174 C 6.4 Microcode Disks?

[Jim Stefanik]

Simon Systems should be able to get you the microcode diskettes. I think they charged me around $35 USD when I bought in Nov. 2017.  Send them an email and let them know what you need.

On a side note, I may need to ping you off list...I've got an 11R and I'm curious if it can be converted to an 11L, since I'd prefer to channel attach it to my machine instead of use ethernet.

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.
